About the Pro-Ject MaiA DS
Small amp with a big sound
The Pro-Ject MaiA DS can handle all your digital and analog music sources, plus Bluetooth for wireless music streaming.
Small amp with a big sound
If you crave the kind of effortless, detailed sound that comes from big integrated amplifiers, but lack the space, check out Pro-Ject's MaiA DS. This tiny amp packs all of the features and punch you'd normally expect with a full-size amp, but in a form factor that can easily fit on a small shelf or tabletop. The super-compact MaiA DS is perfect for powering a pair of speakers to satisfying levels in a living room, bedroom, or home office.
With its built-in DAC (digital-to-analog converter), Bluetooth® streaming, plus an array of digital and analog inputs, the MaiA DS is ready to play beautiful music from a wide variety of sources such as smartphones, disc players, a TV, or a computer.
High-resolution sound, and more
The MaiA DS's built-in DAC faithfully renders your digital sources, including both PCM and DSD high-res music files. The asynchronous USB input provides a low-jitter connection for your computer to ensure the highest possible fidelity.
One coaxial and two optical digital audio inputs means this amp is also ready for CD and Blu-ray players, network streaming devices, and more. Four analog RCA inputs, including a phono input with a high-performance preamp for moving magnet or moving coil cartridges, provide plenty of connectivity for your legacy audio products. Plus, if you ever need more power or bass, it's easy to connect a powered subwoofer or outboard power amp using the MiaA DS's preamp outputs.

Pro-Ject MaiA DS reviews
I have this amp driving B&W CM1 speakers and the sound is excellent. I am using in a large room. Very smooth and musical. The music source is Arcam rPlay which is also excellent. I would say it is a small difference between this setup and a 20,000 setup. The amp can also be upgraded to double the power by adding the Maia linear power supply but not necessary for me
Pros: Fantastic sound and excellent build quality.
Cons: Speaker wire posts are close together requires caution.

I ordered this device earlier this month, August 2017. Upon arrival and unboxing / setting up, I found the bluetooth antenna connection to be of flimsy design and promptly sent the unit back for refund. I commend Crutchfield for the quick refund. If I could give Pro-Ject zero stars for this device I would.
Cons: high cost, flimsy design.

This unit was purchased to replace a fullsize Onkyo A/V Receiver for an audio only setup. Prior to purchase I was not familiar with the MaiA, but liked the features, form factor (small) and 50 watt capability (and that it can be upgraded to 80w). The quality of sound that comes out of the MaiA is a significant upgrade over the 5 year old Onkyo. I have a pair of Sony Floorstanding SS-F6000 (inexpensive) speakers that were once on the chopping block, and now the MaiA has saved them, they sound great! I also like that there very little heat comes out of the unit, could easily be tucked away in a small cabinet.
Pros: Small size, big power. Simple setup. Sub output, Phono input

This is a great product. Simple to set up works great with my Pro-ject turntable. I also stream with Tidal and it sound incrediable. Well worth the money spent.
Pros: Simple to set up. Dedicated sub woofer out. Great companion to the Pro-ject turntable

This is the best thing that has ever happened to my Sennheiser 540HD Reference Gold headphones. What a beautiful sound! Headphone out is dead quiet, fine with the demanding 600O load, and puts out no discernible distortion. D-A conversion is transparent and detailed. I use line-level output to drive a set of powered Bose Companion 3 II desk speakers/subwoofer. They're hardly audiophile, so I have little to say beyond the obvious: The speakers sound as good as they're capable. I have no real speakers to test against yet. Someone else will have to write that review. Pro-Ject's dedication to quality is clear. The amplifier is the successor to the deeply respected Flying Moles Class D "dual-mono" amplifier technology, which is what allows them to get away with such a small package. Output power is limited only by its power supply. If you find you need more, you can get an outboard power supply to take it to 2x80 watts. The amp clicks whenever the digital signal cuts in or out. It's no problem when playing music, but when connected to a computer digitally, the signal can cut in and out frequently and you're going to get a solenoid click each time. I don't need the full power of this DS yet, so I toyed with buying the smaller MaiA. But, I really wanted the pre-amp outs, and so I sprang the extra $500. That is a lot for connections and 30W/channel extra power. Between the clicking and the price difference, I dinged one star.
Pros: Small size High output power for size Power use efficiency Excellent digital-to-analogue converters Excellent amplifier quality
Cons: High price increment over the smaller version. Solenoid-like clicking sound when digital signal starts or stops.

Stereo Integrated Amplifier: The Pro-Ject MaiA DS integrated amplifier is rated at 40 watts x 2 channel @ 8Ω or 55 watts x 2 channel @ 4Ω.
24-Bit/192kHz DAC: The Pro-Ject MaiA DS utilizes a 24-bit/192kHz Texas Instrument multi-bit delta-sigma DAC (PCM1796) for exceptional sound quality from the unit's USB-B input, optical & coaxial digital inputs, and built-in Bluetooth.
Asynchronous USB-B Input: The Pro-Ject integrate amp provides a USB-B input to connect your Windows PC or Mac computer for playback of compressed and high-res music files stored on your laptop or desktop. The unit's USB-B input bypass the inferior DAC in your computer and utilizes the 24-bit/192kHz DAC of the MaiA DS for exceptional sound quality. Asynchronous technology allows the digital clock inside MaiA DS to control the flow of data coming from your computer. This method of communication leads to less jitter (timing errors) for the unit's built-in DAC to deal with which results in clearer more defined sound. The unit supports PCM (up to 24-bit/192kHz) and DSD (up to 5.6MHz/1-bit) music files.
Note: Windows PC will require a USB Class 2 driver that is installed on the included CD-ROM. Mac computers do not require a separate USB driver.

In addition to support for the standard SBC Bluetooth audio codec, the MaiA DS offers support aptX for higher quality audio streaming from select Android devices. aptX audio coding technology provides even better sound quality with lossless, CD-quality streaming for compatible aptX-compatible smartphones, like many Android smartphones with OS 4.0+. The MaiA DS can pair with up to 8 Bluetooth devices, but only one can be used at a time. You'll still continue to use your Bluetooth device to control music playback and view song/artist information.
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 Pro-Ject MaiA DS.
Optical & Coaxial Digital Inputs: The Pro-Ject MaiA DS features two optical (toslink) digital inputs and one coaxial (RCA) digital input to connect your Blu-ray/DVD player, cable/satellite box, game system, or TV. These digital inputs will accept 2ch PCM only. The optical digital inputs support up to 24-bit/96kHz, while the coaxial digital input supports up to 24-bit/192kHz.
Line-Level Inputs: The MaiA DS includes three sets of stereo RCA inputs for connection of an analog audio device, like a CD player, AM/FM tuner, or tape deck.
Phono Input: The Pro-Ject integrated amplifier is equipped with a Phono input for connection of a turntable with an MM or MC cartridge.
Binding Post Speaker Terminals: The MaiA DS integrated amp is fitted with two pair of binding post speaker terminals which will accept bare wire (up to 12AWG), pin-connectors, spade-connectors, and banana plugs (single only).
Sub Output: The Pro-Ject MaiA DS is fitted with a mono-subwoofer output for connecting a powered sub.
Headphone Jack: There is a 1/4" headphone jack on the front-panel for connecting a set of headphones (16-600 ohms).
Fixed & Variable Line-Level Outputs: The Fixed stereo RCA output can be used to connect a recording device. The Variable stereo RCA output can be used to connect a power amplifier or active loudspeakers.
Simple Control: The Pro-Ject MaiA DS includes an IR remote control for wireless operation of the integrated amplifier. Control options include Power On/Off, Input Select, and Volume Up/Down. These same controls are also located on the unit's front-panel. You can also download the free Box Control app from Apple's App Store or GooglePlay onto your Bluetooth-paired Apple iOS (5.1.1+) or Android (2.3.3+) device and control the MaiA DS from your mobile device.
12V Triggers: The Pro-Ject MaiA DS integrated amplifier features a 12V trigger input and output for remote turn-on. These 12V triggers consist of a 3.5mm jack.
