Our take on the Peachtree Decco2

With its trailblazing Decco amplifier, Peachtree Audio hit on a winning formula for the download generation — a high current integrated amp with a vacuum tube preamp stage mated to a high-performance digital-to-analog converter. A USB input made it surprisingly simple to enjoy high-fidelity sound when using a computer as a music source. The vacuum tube made digital music sound surprisingly organic.

We apologize, but due to unexpected demand the Decco2 is no longer available. Please call an advisor at 1-888-955-6000 for other options.

With its trailblazing Decco amplifier, Peachtree Audio hit on a winning formula for the download generation — a high current integrated amp with a vacuum tube preamp stage mated to a high-performance digital-to-analog converter. A USB input made it surprisingly simple to enjoy high-fidelity sound when using a computer as a music source. The vacuum tube made digital music sound surprisingly organic.

The new Decco2 improves on the original, by incorporating the acclaimed ESS Sabre DAC. The Sabre DAC "upsamples" your music files to 24-bit/96kHz resolution and filters out "jitter" (digital timing errors). The result is digital music that sounds remarkably clean and lifelike, with three-dimensional stereo imaging. The DAC filter slope switch let you choose a fast slope that measures better on a test bench or a slow slope that sounds better to some listeners.

The Decco 2 back panel

The back panel features a "sharp/slow" filter switch that helps fine tune the sound to your listening preferences. You also get variable and fixed line out, so you can connect a subwoofer or an external amp.

The Decco2's optical and coaxial inputs make it easy to connect your other digital sources such as a CD player, music server, or a music streamer like the Logitech® Squeezebox™ Duet. The Decco also makes an ideal companion to the Wadia 170iTransport for getting better sound from your iPod.

Crutchfield Customer Review (What's this?)

Very easy setup, space for Sonos makes for a clean setup, very simple interface sound performance is awesome, feeling very good about going completely digital.

Pros: sound, look, easy setup, sonos integration

Cons: not much, sound control on remote is not very subtle.

Great Sound Quality

Crutchfield Customer Review (What's this?)

I primarily use a Sonos system with Rhapsody and more recently MOG and in my office I've been using the Sonos unit that comes with a built in amp. This has been convenient but the sound a bit muddy. So I decided I wanted to upgrade my system and went for the Decco2. I hooked it up with a digital connection to the Sonos with a coax cable and found it to sound nice but it didn't blow me away. Then I happened to read something in the owners manual that said not to use a standard cable but rather a specific hi-fi coax cable which I immediately ordered. After I hooked up the cable and turned on the system I was blown away. The depth of the sound is amazing. Even my 9 year old said it sounded incredible. I definitely recommend this amp.

Crutchfield Customer Review (What's this?)

I stream music from my mac to an Airport, then use the Airport's Toslink (optical) out to input into the Peachtree Decco 2. The pre-amp outs in turn feed a NAD poweramplifier. This powers my whole-house sound system, which is 5.5" Boston Acoustics speakers. Before getting the Peachtree I used a 15 year old Dennon integrated amp (again, feeding the NAD power amp). I am able to use the fine-lock with respect to the digital signal. I use the soft curve for the DAC, which Peachtree says most people prefer. I haven't compared the two settings in detail. I also attached a radio receiver, tape player, and CD player to the Decco. This uses up all the analog inputs, so I cannot attach my turntable. In reality, I use the turntable and tape player infrequently, but still it is annoying to not have enough connections. Also, I have a subwoofer and since I am using the pre-outs already, I cannot attach the subwoofer, or have to split the signal, which seems like a bad idea. The Decco is about the size of a normal amplifier, but looks quite different. The fit and finish seems very good. Personally, I'd like to see a numeric display of the volume and a numeric display of the sampling rate incoming (e.g., 45 kHz), but that would impair the aesthetics of the device.

Pros: The Peachtree Decco 2 made a big difference in sound quality. In particular, the whole lower part of the sound spectrum, from deep bass though middle tones. In addition, everything is much crisper. I cannot tell a difference when I turn the tube preamp on and off, but it does look cool.

Cons: Number of inputs. Lack of subwoofer out.

More power please!

Crutchfield Customer Review (What's this?)

I have to agree with the first reviewer. This is a great amp, especially with so many features. I love the DAC and preamp section - but the power amp is missing the oomph. The female vocal is nice, but the bass seems too rounded. If a separate power is added, this can be very nice. For the money, this still is a steal.

Pros: Warm sound, nice female vocal, great features

Cons: Detail missing, bass too rounded

Sooo close to perfect

Crutchfield Customer Review (What's this?)

I bought this Decco 2 from Crutchfield and was really pleased with the service thorough the order process. I also bought a pair of Polk Audio RTi A1s to make a small, pretty accurate system. After listening to this Decco 2 for a couple of months now, I really like the quality of sound I get from this component. I've got a Toshiba DVD player as a transport and the quality of sound I get from the Decco /Toshiba/Polk combination is head and shoulders above my Yamaha receiver/Panasonic Bluray/Klipsch home theater. Really good recordings sound phenomenal, but bad recordings still sound bad. The only complaint I have about the Decco 2 is the amplifier. The 40 wpc is so clean, but if you listen to a recording that requires a little more emphasis you can hear that the Decco just doesn't have it. It doesn't sound bad, it's more like the Decco is saying "that's all I've got." Specifically, listen to a good jazz recording where the drums haven't been compressed to death and the drummer is just getting it and you'll know what I mean. After searching the internet for people's thoughts about this component and I'm finding that many people are using the Decco 2 with a good power amp and getting phenomenal results. Until I can do that myself I'll continue to enjoy it as it is, and if I need a little more volume and kick, I'll plug in my headphones and be just fine.

Product Research


Overview: The Peachtree Audio Decco² is an audiophile-grade 40 watt x two-channel hybrid integrated amplifier. The preamp's Class-A tube buffer tames harsh compressed digital music and allows exceptional reproduction when listening to high resolution files. The high-current amplifier section then powers your speakers. In addition to the internal amplifier, the preamp also feeds the preamp output (for use with an outboard amp or powered subwoofer), the fixed line output (for using the Decco² as a stand-alone DAC), and the Class-A tube headphone section.

DAC (Digital to Analog Converter): The Decco² includes the ESS 9006 Sabre DAC, a mutli-layer board with over 450 components and 11 regulated power supplies. The ESS Sabre DAC's patented jitter reduction circuit re-clocks the digital signal before passing it through a high-resolution 24/96 upsampling processor, perfect for computers and most streaming or hard-drive based music servers because they typically have high levels of jitter (digital timing error between the source and the DAC). Each digital input is transformer-coupled so noise associated with ground loops and switching power supplies from computers is eliminated.

USB Connection: Using the Decco², you can take pure digital audio signals from iTunes, Windows Media Player, Front Row, or any other music management system on your computer before it goes through a sound card. Just connect USB cable between your computer and the Decco²'s USB type-B port; no sound card is required.

Controls: The Decco² has the following controls (input voltage, filter slope, and jitter bandwidth are on the rear-panel):

  • Power: on/standby
  • Input Selectors: five discrete input buttons; USB/Coaxial/Optical/Aux 1/Aux 2
  • Volume: rotary volume control; the knob is motorized and turns when you adjust the volume using the remote control
  • Filter Slope: the slope of the DAC's digital filter is switchable; fast/slow
  • Jitter Bandwidth: wide/narrow
  • Voltage Switch: the input voltage is switchable for international use; 115V/230V

Remote Control: An easy to use IR remote control is included with the Decco²; it offers the same functions as the front-panel controls, plus adds mute and tube buttons (the tube button toggles between solid state and tube-hybrid operation of the preamp). The remote control IR sensor is located in the center of the Decco²'s front-panel.

Connections: The Peachtree Audio Decco² features the following connections (all but the headphone output are on the rear-panel):

  • Aux 1 and Aux 2: two sets of analog stereo RCA inputs
  • Optical Digital Input: Toslink input
  • Coaxial Digital Input: single RCA input
  • USB Input: USB type-B port; takes digital audio content from your computer and sends it to the internal DAC
  • Pre-Out: stereo RCA preamp-outputs allow you to use an external amplifier or a powered subwoofer
  • Fixed Line Output: the Class A fixed line output (stereo RCA) allows you to use the Decco² as a stand alone DAC
  • Speaker Terminals: left and right binding-post speaker terminals; will accept spade, single banana, or pin connectors and bare wire up to 8-gauge
  • Remote in/out: 3.5mm remote input and output jacks
  • AC Input: three-prong detachable power cord is included
  • Headphone Output: front-panel, 1/4" headphone output; the speakers are muted when headphones are plugged in

Tube Window: The Decco² features a tube window, allowing you to view the glow of the unit's tube. The blue LED under the tube is lit when the preamp is in tube-hybrid mode.
