Sweet sound in small spaces

If your bookshelf speakers are yearning for a versatile, compact integrated amp, check out the TEAC AI-301DA. It's a great choice for a bedroom or office where ho-hum sound just isn't going to do it for you. Conservatively rated at 22 watts per channel, this little amp is poised to impress. Plus, it offers analog and digital connections, so you can play music from a wide variety of sources such as disc players, a TV, or a computer.

Pristine playback from your computer and other digital sources

It's easy to feed your digital music to this amp. Connect your computer via the asynchronous USB input and enjoy your entire library of digital tunes through your favorite speakers. The AI-301DA is compatible with high-resolution files, including DSD files and 24-bit/192kHz PCM files. An audiophile-quality Burr-Brown digital-to-analog converter (DAC) makes the most of them, for outstanding levels of detail and dynamic range. (Those MP3s will sound pretty good, too.) Optical and coaxial digital audio inputs let you connect other sources like a TV, CD or Blu-ray player, or a network streaming device like a Sonos CONNECT.

Bluetooth on board for smartphone streaming

Wired connections aren't the only way to enjoy digital music with this amp. Stream tunes wirelessly from your smartphone or tablet thanks to built-in Bluetooth. You can listen to music stored on your device, streamed from online music services like Pandora® and Spotify®, and from YouTube™ and other apps. The AI-301DA is also compatible with aptX™, for sound quality that's as good as Bluetooth gets when streamed from an aptX compatible device.

very satisfied

Written By Marty- GA, Georgia on Friday, August 28, 2015

Crutchfield Customer Review (What's this?)

Overall it's a really nice unit. It's not as lively as the starter model nad that died on me ... But it is a fantastic value. Bluetooth connection from my I phone works great and easy to sync. Analog inputs work well. It does most everything I need it to do. Easy to set up and I love the compact size. It has plenty of power to drive my totem acoustic rainmakers. I have listened to a few recordings where an eq or tone would be nice but most of the time the sound is pretty true. I considered the sprout because of the phono pre, but for half the price I didn't mind running my old technics turntable through the preamp I already owned. Overall I'm very satisfied.

Pros: Good value. Easy to setup and use. Compact size. Good sound quality. Extremely versatile.

Cons: No tone or eq.

Good Product From Old Name

Written By Larry D, Millington, Tennessee on Sunday, July 26, 2015

Crutchfield Customer Review (What's this?)

The Teac name goes back a long way and has always made a fine product. No exception here, as this da converter does its job well.

Pros: Easy to use. Has a small footprint.

Cons: Could stand a little more power, but not a deal breaker.

Nice little amp

Written By ComposerD, Florida on Monday, July 06, 2015

Crutchfield Customer Review (What's this?)

Nice little amp. If space is a concern, this amp will do fine. Doesn't quite have the oomph of my mid-70s Kenwood that the Teac replaced. But, it doesn't have to fill the same kind of space. So, it'll do. Wish it came with a built-in phono pre-amp for the price, though.

Pros: Space saver

Cons: Not super powerful. No phono pre-amp.

Excellent value

Written By Mike B, San Francisco, CA on Wednesday, July 01, 2015

Crutchfield Customer Review (What's this?)

Offers a lot of quality features in an affordable, small footprint. Amp seems especially detailed and clean, like the better quality digital amps. I'd say overall has an overall warm presentation which I like but for the headphine amp found it somewhat too much of a good thing when paired with my grados.

Pros: Great value, very versatile

Cons: Slightly less detailed, but may be s good thing with lossy files.

Excellent Little Amp

Written By Charles K, NYC on Tuesday, June 16, 2015

Crutchfield Customer Review (What's this?)

Replaced a really old Yamaha receiver with this TEAC Amp. I am running Bowers & Wilkins CM5 speakers and this amp sounds great! It was a debate between the NAD and TEAC and basically the price was the deciding factor here. The number of inputs, remote control, sound quality and size factor made this a perfect combo. I gave my AppleTV connected to the optical input and now have complete control using the Harmony Remote App and Airplay. I didn't even mess with the bluetooth option.

Pros: Sounds Quality, Size, Price, Input Options

Cons: Maybe too many inputs. Expensive Pre-Sale price (Make 1 analog & 1 digital input, remove bluetooth and get the retail price to match the sale price.)

It Works

Written By Stephen, California on Tuesday, June 16, 2015

Crutchfield Customer Review (What's this?)

I got this to replace an old (20 years) component system. A bunch of parts were replaced with this one box. It works fine. With my old tower speakers, the sound fills the room. The bluetooth link seems to drop out some when my macbook pro (2008 era) is more then around 10ft, but I've had that problem with other bluetooth speakers, so it may be a macbook issue. Not sure. It doesn't have a lot of inputs (2 RCA, 1 digital, 1 USB, and 1 bluetooth) but I don't have a lot of potential sources, so I'm fine.

The remote control works fine, and it not cluttered with a gazillion useless buttons.

Pros: It works, at a good price. Sound is fine.

Cons: Not many input sources


Written By Bluerainbug, San Diego, CA on Saturday, May 23, 2015

Crutchfield Customer Review (What's this?)

I'd say this is a good product, well built and engineered. I use it with a pair of JBL loft 40's. Sound is superb, though I'm not using the DAC, it has plenty of headroom for my speakers.

Pros: The price after rebate is justifiably right. I wouldn't pay more than that for what it is.

Cons: It's really just an amp with no tone, bass or treble controls.

Powerful and versatile little amplifier

Written By NickH, Ohio on Friday, May 22, 2015

Crutchfield Customer Review (What's this?)

I looked at several different mini integrated amplifiers and actually purchased a NuForce DDA-120 amplifier from another electronics seller on the Internet and was very disappointed by its extremely grainy and harsh sound. I tried it with several different speakers and all had the poor, grainy sound. I assumed it was a defective unit and sent it back to the seller for a refund. At this time, I noticed the Teac AI-301DA on sale at Crutchfield and with a $100 rebate, too. So, at less than half the overall cost (with rebate) of the NuForce amp, I purchased the Teac amp and received a very clear, clean, detailed little amplifier that actually fits my needs much better with its multiple analog inputs along with the several digital inputs. Currently, I have it powering a pair of efficient BIC bookshelf speakers with it connected by the coaxial digital input from a Sony CD player, and the sound coming from them is as good as I have ever heard. It has plenty of power to drive these speakers to an extremely loud volume. The soundstage is very good and the sounds are distinct and easily located, not at all smeared and hard to distinguish the instruments and vocals locations. In fact, on a few cd's I am hearing some things I haven't heard before. But the one feature I really like is the auto "on" and "off" feature via the digital inputs. I can just start the CD player playing a disc and it automatically turns on and amplifies the music. Nice little amp.

Pros: Auto "on" and "off" features via the digital inputs. Clean, pretty powerful sound for its size.

Cons: None so far.

Better than expected

Written By Todd P, New York on Wednesday, April 29, 2015

Crutchfield Customer Review (What's this?)

I was not sure what to expect as this integrated amp has a rating of 20 watts of power output. I have a number of other high end audio gear that is have invested in and collected. I needed a device with a small form factor that would fit into a wall unit. My goal was to power a pair of older inefficient floor standing speakers. I connected a SurfacePro2 with docking station as my audio source as I am a Spotify premium user as well as a digital optical out of my large screen TV. The room is a 15' by 20'. I initially purchased a Micro Audio system and the sound was like a boom box with low fidelity. Crutchfield advertised a 30 day return policy so I figured I would give the amp a try. I plugged it in setup was easy and that was it. Once I turned it on I was sold. The sound was rich and full. The power and overall volume of this amp is outstanding. It powered my old inefficient speakers easily and the base is powerful and more than sufficient. I have a sub I was planning on using and after a little while of listening I decided I did not need it. The USB digital direct connection was another surprise. The premium sound from Spotify is near HD Audio quality, just don't forget to select the HQ setting in Spotify premium. Crutchfield shipped the item quickly and the order was a very easy process. Overall the was a premium transaction, great price and amazing product.

Pros: Fit and Finish, Power output, form factor, digital direct USB, soft switching between inputs, Sub out,

Cons: Remote is marginal usable, everything else is great

Great Value at Sale Price

Written By MikeJ, Buffalo, NY on Wednesday, April 22, 2015

Crutchfield Customer Review (What's this?)

I have been looking of a versatile digital amp for sometime. I love the connection flexibility that the TEAC AI 301DA offers. (usb, optical, BT, plus two analog) Paired with relatively sensitive speakers this amp really preforms well. (Klipsch RB 61 ii), but also sounds great with a pair of 30 year old Realistic bookshelf speakers i had laying around. Do not be swayed by the low watt rating, you get terrific sound quality, as loud as would ever need. Sounds great with Spotify. sub out alos a plus

Pros: Compact Attractive and well built Sound quality is great A great value at current sale price +rebate Subwoofer output


Written By MikeS, Philadelphia, PA on Tuesday, April 07, 2015

Crutchfield Customer Review (What's this?)

I've owned the TEAC A-H01 for the last year basically to power a pair of Polk Audio in-wall speakers in our living room. Used mainly for background music at dinner parties, etc., the A-H01 fit the bill perfectly except perhaps for bass response which is a tad anemic. I've replaced the A-H01 with the AI-301DA for 2 reasons - 1) the remote on the A-H01 lacks an on/off function which makes it awkward to use with a universal remote and 2) the AI-301DA features Bluetooth otherwise, I suspect that the internal are similar if not identical in all other respects.

Pros: Small and light form factor, substantial sound field for a diminutive integrated amp.

Cons: Bass response is a bit anemic.

Good sound but poor QC

Written By bruce, Massachusetts on Saturday, April 04, 2015

Crutchfield Customer Review (What's this?)

I bought this for a bedroom system and really wanted to like it. The first unit I received had a loud buzz over the headphone jack and a softer buzz over the speakers. Touching the case anywhere would reduce the noise - so it seemed like a grounding / switching power supply issue - all other audio equipment using the same electric outlet have no problem. The unit was now out of stock, so Crutchfield sent me a new unit once back in stock. First thing I did with unit #2 was try the headphones and then the speakers - dead silent - great sound. Fantastic sound when streaming for my macbook over bluetooth. Then I switched to my iPhone, still great sound - then I tried to adjust the volume from my iPhone - no adjustment, it would just go from full volume to off.

Then tried the following: 1) unpair / repair the iPhone from unit #2 - still did not work - My iPhone works fine with the 5+ other bluetooth devices 2) reboot phone 3) tried above 3-4 times 4) paired an iPad to unit #2 - still no volume control 5) reconnected from my macbook - volume control works fine on unit #2 6) pulled unit #1 out again - volume control works under all conditions (iPhone, iPad, mac)

The manual also says that the Teac remote supports controlling the bluetooth device (ff, rw, play, pause) via AVRC but this did not work on either unit. This same capability works fine in my car.

So back to Crutchfield for unit #2 - now willing to role the dice again, I'm going to try the NAD D3020 now.

Pros: nice looking, great size. I was able to verify support for ACC codec by doing a bluetooth packet capture. Great sound on unit #2 More than enough power for some stand mount speakers (wharefdale diamond) - I'm impressed with ICEpower on the unit without the buzz.

Cons: Poor quality on the two units I tried - just unlucky perhaps? If you don't need bluetooth, you may be fine.

OK For Limited Budget Solution

Written By JohnM, Texas on Friday, April 03, 2015

Crutchfield Customer Review (What's this?)

This integrated represents a good value when bought at recent sale prices. That said, there is a noticeable bump in the mid range and softness in both the lower bass and upper treble regions from this unit. Vocals, in particular, are overemphasized and forward while there is a noticeable lack of oomph in the lower bass (compared to my reference external Sabre ESS DAC via one of the Teac's analog inputs). The upper treble region lacks full extension so upper frequency details are simply missing from content that contains it. On the plus side, the amp section is punchy and outputs a surprising amount of power for its rating. I was able to easily drive my inefficient Magnepan .7 (4 Ohm) speakers to room filling volume. The amp delivers plenty of detail and resolution and the soundstage and sense of depth reproduction is also surprisingly impressive. That said, music sounds a little "hard" or electronic due to the over emphasized mids and soft bass and treble response. All in all, if you are on a strict budget and looking for an all-in-one integrated that includes Bluetooth, then this little guy is a solid choice at the current sale price. If the price moves up closer to the NAD 3020D, then you probably should consider the NAD for the more musical/naturally sounding DAC and amp (but you will be giving up the Teac's hi res capabilities via the USB input!).

Pros: Punchy amp delivers power beyond its modest rating Great Depth and Soundstage with Etched Resolution Aptx Bluetooth Support for DSD All-in-One Solution for a Reasonable Price

Cons: Forward Midrange with Recessed Highs and Lows Slightly "Hard" Sound

Product Research


Class-D Amplifier Circuit: The power amplifier stage is based upon a tried and tested Class-D amp, manufactured by ICEpower of Denmark. It converts a high-resolution sound source into high-definition speaker signals using a feedback loop between a hybrid feedback controlled oscillating modulator (HCOM) which faithfully amplifies the signal, and a multivariable enhanced cascade control (MECC). The efficient design of the 43W + 43W (4Ω) or 22W + 22W (8Ω)  amplifier creates very little heat, eliminating any need for a cooling fan, thus affording a quiet environment that's ideal for musical appreciation.

Burr Brown DAC: The TEAC AI-301DA uses a Burr Brown 1795 DACs for high performance and support of a wide range of digital audio sources. Its three digital inputs (optical/coaxial/USB) support sampling rates of 32, 44.1, 48, 88.2, 96, 176.4, and 192kHz. It's ideal for playback of FLAC, WAV, Apple Lossless, and other high-resolution file formats. It is capable of 32-bit processing and even has the capacity to process 2.8/5.6MHz DSD data, for faithful and accurate playback of high-resolution sound sources.

Asynchronous USB Input: The TEAC AI-301DA features a USB (type-B) port for connecting your Windows PC or Mac computer. The AI-301DA accepts digital audio source material stored on your computer at up to 32-bit/192kHz. When receiving digital audio signals from a computer via USB cable, the unit can operate in asynchronous mode, controlling the timing of the input signal using the AI-301DA's internal clock. With asynchronous transmission over USB, signal compromising jitter is effectively eliminated, allowing digital audio signals to be transmitted in a pure, unadulterated state. This allows optimal playback of high-resolution digital audio files from playlists/libraries in your iTunes, Windows Media Player, or similar playback programs on your computer.

Note: Compatible with Windows XP (32-bit), Vista (32/64-bit), 7 (32/64-bit), 8 (32/64-bit), and 8.1 (32/64-bit); Windows computer will also require the installation of a dedicated TEAC USB driver. Compatible with Macintosh OS X Snow Leopard (10.6), OS X Lion (10.7), OS X Mountain Lion (10.8), OS X Mavericks (10.9); no additional driver required for Macintosh computers.

HR Audio Player App (for Windows & Mac): The TEAC HR Audio Player is a free application software download to help you playback and enjoy your high-resolution audio files on your Windows or Mac computer with ease through the TEAC AI-301DA and connected speakers. The TEAC HR Audio Player allows you to listen to your audio as soon as you connect the TEAC AI-301DA and install the application; simply drag-and-drop the music files on your computer into the window of the application. Various high-resolution audio files formats are supported, including DSD (2.8MHz/5.6MHz), PCM (44.1-192kHz; 16-32-bit), and FLAC (44.1-192kHz; 16-32-bit), plus compressed music files like MP3 (32-320kbps). You can even choose between ASIO2.1 and DoP (DSD over PCM) modes when playing back DSD files from your Windows PC. In order to maximize the connected unit's performance, a simplified screen of the TEAC HR Audio Player helps reduce CPU load time while data processing.  Furthermore, the RAM Buffer Playback mode that stores the audio data onto the internal memory is supported for the ultimate digital audio playback conditions. Additional features include Playlist, Repeat, and Shuffle playback.

Note: Compatible with Windows XP (32-bit), Vista (32/64-bit),  and 7 (32/64-bit). Compatible with Macintosh OS X Lion (10.7) or later.

Optical & Coaxial Digital Inputs: The TEAC AI-301DA is fitted with optical (toslink) and coaxial (RCA) digital inputs for connection of other digital audio sources like your CD/SACD, Blu-ray/DVD player, or network player. These digital inputs will accept two channel linear PCM (not Dolby Digital/DTS). The coaxial digital input supports 32, 44.1, 48, 88.2, 96, 176.4, and 192kHz sampling frequencies (16- or 24-bit). The optical digital input supports only 32, 44.1, 48, 88.2, and 96kHz sampling frequencies (16-or 24-bit).

Analog Inputs: The TEAC AI-301DA features two sets of stereo RCA inputs for connecting an external analog audio source, such as your CD player, Tuner, or Tape Deck.

Built-in Bluetooth w/ aptX: The TEAC USB DAC amplifier features built-in Bluetooth (version 2.1 + EDR) with support for A2DP, AVRCP, and aptX. You'll be able to stream stored music and music apps from your Bluetooth-enabled Apple iPod/iPhone, iPad, Android smartphone/tablet, Windows PC, Mac computer, or other Bluetooth-compatible devices to the TEAC AI-301DA. You'll also be able to control basic music playback functions (Play/Pause & Previous/Next Track) from the included IR remote. The USB DAC amplifier evens employs aptX audio coding technology for lossless, CD-quality streaming with compatible AptX-compatible phones (like some Androids). Up to 8 devices can be paired with the AI-301DA, but only one device can be used at a time.

Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the TEAC AI-301DA.

Binding-Post Speaker Terminals: The TEAC AI-301DA USB DAC amplifier is equipped with four binding-post speaker terminals to connect a pair of loudspeakers (4-8Ω). The binding-post speaker terminals will accept bare wire (up to 8AWG), spade-connectors, pin-connectors, and banana plugs (single or dual).

Note: Combine the AI301-DA USB DAC amplifier with TEAC's LS-301 coaxial loudspeakers (sold separately). The LS-301 speakers have been specifically developed to match the AI301-DA to create a system that does full justice to any high-resolution audio source.

Sub Output: The TEAC USB DAC amplifier is fitted with a single mono-RCA output for connecting a powered subwoofer. There is no built-in crossover in the AI301-DA. You will need to use the built-in low-pass crossover of your powered sub.

Headphone Amplifier: The TEAC AI-301DA features a built-in headphone amplifier and front-panel 1/4" headphone jack that will accept headphone impedances from 8 to 600-ohms. The 100mW + 100mW output (at 32-ohms load) headphone amplifier uses CCLC (Coupling Capacitor Less Circuit) technology. In conventional headphone output circuits, a capacitor is used for output-stage coupling, and so the sound is unavoidably colored. When the capacitor is combined with a high-pass filter this often results in phase lags, or low frequency level degradation. With CCLC the negative impact of capacitors on sound quality is eliminated, providing full low-frequency sound and a responsive headphone listening environment with great spatiality.

Remote Control: The TEAC USB DAC amplifier comes with a IR remote for wireless operation of the AI-301DA. The remote offers Power, Volume, Input, and Playback controls.

All-Metal Chassis: The TEAC AI-301DA features a compact chassis with aluminum panels and a motor-driven volume knob with the tactile feel you'd expect from controls found in high end full-size hi-fi components. The solid all-metal chassis is impressively inert, minimizing the effects of vibration on the unit's sound quality.

Auto Power On: The AI-301DA has an Auto Power On function which automatically switches on the amplifier's power when it senses a digital signal input. When the amplifier is connected to optical digital audio output from a television set, just switching on the television turns on the power of the AI-301DA, enabling you to immediately enjoy high-quality sound without having to adjust any other settings. This facility makes life very convenient allowing you to switch on the TV and instantly listen to music or a soundtrack.

Auto Power Down: If there is not signal from the selected input source and no operation has occurred for approximately 30 minutes, the USB DAC amplifier will enter standby mode. Power consumption in standby mode is 0.5W or less.
