Woah, the sock design is possibly the very first Ive seen. Im impressed. Truly, a masterpiece of engineering.
I haven't posted here for quite a while. Just completed a 'scrapheap challenge' gainclone power amp using 2 SMPS in series for a power supply (the white/alu thing) and 2 LM3875 chips in the gainclone itself (the green rat's nest). They are fed by a DCB1 buffer/preamp (the thing under a clear acrylic cover) with an external 'swappable' volume control (the thing with a pot on a stick)!

First attempt at a Gainclone.
Uses the Audiosector LM3875 kit, a scrap bit of MDF, an upturned pine tray and old aluminium channel. Incorporates a Raspberry Pi and PiDAC from IQAudio.com together with a cheap DAC from eBay with a TosLink to bring audio in from my TV.
Just a prototype really but delighted with the sound.

I see you have a Pi in there. I've been thinking the same thing; Pi, onboard DAC and power amp. I'm currently running two Pis a 2 with HiFiBerry + DAC and a 3 with USB XMOS DSD external DAC brd. I love them. Currently my 3is hooked to my 1920s power amp.

@mhouston. Yes the pi works really well. I've finally managed to get my hands on a pi zero so that will be the next project.
The pi zero is a cut down version of the pi. Half the size yet more powerful than the original pi it is ideal for embedded projects or, in my case headless music player. The zero itself costs the grand sum of £4 though one must add on to that the cost of psu, wifi etc. Still significantly cheaper than its big brother which I'll be able to repurpose for something else.
Unfortunately the zero has proved to be very popular since its release which makes it hard to get hold of at the moment.
Without having to TTY in and and configuring (VI) any config files does it run Rune and\or Volumio 2. Does it support multiple USB sources, support the N150 wifi dongle?
And with no code or config file hacking require da??

I just picked up 2 Pi Zeros yesterday at Micro Center in the US. I did pay more for them in a starter kit, but they were still only $20 with a nice wall-wart, and cables. That was 1/3 off the normal price. I'm planning an integrated amp/streaming device with a 5" touch screen. To include; remote source selection, volume, streaming and bluetooth connectivity along with normal digital and analog inputs.
Hi redjr,
This project is very interesting for me since I was looking for such a device for a long time. For the time being I am using a Chinese media player as a source but quality is not satisfying. Unfortunately I am not an expert in the field and can hardly manage to build it myself but can try to follow your project if you share the experience.
Otherwise I have a standalone heavy modded DAC based on TDA 1541 A, tube preamp and three power amps driving six speakers.
Please comment,
Thanks
