Ridiculously good amplifier for a $70 board

I've been using a Raspberry Pi with the IQAudIO DAC and Amp boards running Picoreplayer in my main living room stereo system for some weeks now. With speaker wires connected to the amp board via alligator clips, it sounds better than the collection of high end audio amplifiers I have in there. It may be that the lower damping factor caused by higher series resistance from the alligator clips boosts the lower midrange/upper bass where the system was a little lean, or it may just be that good an amplifier, but things sound great. This stack plus a pair of speakers and you have a one-box stereo system front end. Highly recommended.

Awesome products. Forms a super compact hifi stereo.

I just got the PI-DAC and AMP+ in and setup, and I am really impressed with this thing. There are many different TPA3116 amplifier designs out there, but none of the others are made into a RPI hat that stacks and back powers the DAC and PI. I am using the 60W 15V power supply, right now, but want to try this 19.5V 130W smps soon as 19V seems to be the sweet spot with these TI chips. My only complaint is that shipping took a little bit longer then expected, but if I were to guess that was due to the snow storms up north and the USPS. It would be nice to have a fed ex or ups option instead of USPS for the states. The only trouble Ive had is really just being unfamiliar with terminal. I am using volumio right now, and otherwise it is very easy to setup and use as well. I couldn't get the gpio to latch signal for the unmute the other day and just jumpered pin 9, but again its been some time since I used terminal for much of anything. This is turning into one of the coolest stereos I have build. Thanks Gordon. The box in the picture is going to house everything once I get it finished. Review Image

All-in-one device with IQaudio DAC+ and Amp+

I purchased from Tindie a Pi-DAC+ and a Pi-Amp+ with its power supply and installed Picoreplayer with the latest Squeezelite version (1.8) which allows to use DAC+ Alsa hardware to change the volume.

I am very happy with the sound by this amazingly small all in one device through my Q Accoustics 2010i speakers.

A good surprise is that as a alternate use of your streaming device, you can amplify a line-in signal coming from your PC or whatever source : you can just plug it into the RCA plugs of the DAC+ and it works !

Please note this is not officially supported by Gordon at IQaudio, but considering the low voltage of a line-in signal, this should not cause any dammage to your set-up.

Have fun !

A wonderful system for Raspberry pi

I purchased two DAC+, one AMP+/with power brick, and two smoked cases; one for the pi/dac+ combo and one for the pi/dac+/amp+ combo. Everything arrived on time and in perfect condition. The assembly is straight forward and easy.
In both instances, I'm using piCorePlayers which are Raspberry pi boards running Sqeezelite player software.

The PIDAC+ is feeding an Audioengine B2 active speaker, with great results. I have tested the AMP+ on a set of B&W 805 speakers, which are rated 8 ohm and 88 spl. I was pleasantly surprised when I heard the results!
I plan to build a set of Mark Audio Alpair 7.3s and power them with the AMP+.

Gordon is great to work with. I recommend IQaudIO to all the Raspberry pi users out there. Review Image

Forms an amazing all-in-one system, potent for the size!

Please read my review of the Pi-DAC+ for my thoughts on it, as to use the Pi-AMP+ you'll be using the DAC as well.

The amp is dead simple to install and use, like the DAC it just plugs in and four 12mm standoffs brace it very securely. Attach your speaker wires and you're set. To avoid popping through your speakers on power up it starts muted, and an LED on the board shows this clearly. Either bridge two pins on the board with a jumper/switch, or run the commands provided on the support pages to unmute it and then the amp will sing whatever the DAC outputs.

I am frankly amazed with the quality of the output. Previously I ran the Pi-DAC's output to a Topping TP-21 amplifier and I was very happy with the sound, but there is a world of a difference with this amplifier. Most obvious is the power on tap, there is plenty for my floor standing speakers, enough so that I hope the RuneAudio software has a maximum volume setting implemented in future!

After getting past the power level, the quality of the sound impresses. Bass is defined and controlled, gaining proper detail and "texture". Through the mids and treble, everything sounds detailed and smooth, with none of the harshness that has put me off the bulk of the mid level consumer HiFi amps I've heard previously. Vocals sound amazing. I'm spending way too much time just digging through the old collection to listen to favourite tracks again.

The combination of the Pi, Pi-DAC+ and Pi-AMP+ forms a "perfect source unit" for my needs. It is tiny with a single power supply required. In the right enclosure and with a $10 USB wifi adapter plugged into the Pi, this will disappear on a shelf and produce sound that would otherwise take multiple components, power bricks and interconnects to provide. Instead of sacrificing sound quality to do this, it will likely sound better. While admittedly not having much other gear to compare it to directly, I would expect it embarrasses most entry level and mid level consumer audio components.

Obviously I'm happy with the purchase, best dollars I've spent for a long while!
