use 18 gauge wire for hookup
hmm, copy link location and paste into browser, google will open it, and will find even more orThe link doesn't open for me?:scratch2:
Another random project to add to the mix... Bought a pair of M-Audio Studiophile AV 30 speakers at my local thrift store for $5. The internal amp was fried ,as expected, so I popped in a TPA3116 Bluetooth amp I had sitting around. Sounds great! Since the speakers are non-metallic the Bluetooth connects fine to the board hidden inside.
Link to the board I used.

My latest TPA3116 iteration. Dual chip amp, in a wine box purchased for a charitable donation, with source included. At the bottom is the source, a Raspberry Pi with an I2S DAC. I stream FLAC from my router to various Pi's around the house. Nothing less than 44.1khz/16bit CD quality, and all lossless format (no mp3). DAC is capable of 192khz/24bit.
Is it just that simple?

That's very interesting read for everyone who would like to know a bit more. :thmbsp:
Which I2S DAC have you gone for? Is it WM8804G based?
Did you have any preference between the WM8804G, PCM5102 and ES9023?
I'm looking to get one or two for my Raspberry Pi audio systems to replace the dirt cheap USD CM108 DACs I'm using.

First off, I have no equipment or knowledge to electronically test the differences between the DACs, just my ears.
The one in the picture is a PCM5122, and I also have a PCM5102 and an ES9023.
When I got the ES9023 I definitely preferred that over the PCM5102. I think it sounded clearer and more detailed, and this impression has not changed. I found the PCM5102 warmer, and I prefer precision.
This is not to say one is better than the other, they are just different.
I did consider the Wolfson WM8804 based DAC, as they had good reviews. The takeover of Wolfson by Cirrus Logic seems to have created some business issues, which have resulted in poor support, implementation and compatibility issues - the Wolfson board does not appear to be widely supported - so I gave it a miss.
The PCM5122 and the PCM5102 - no difference in sound to me. The PCM5122 does, however use more GPIO pins, and uses I2C to communicate with the Raspberry. If you intent to use something else (eg a small LCD screen) which uses I2C this is an issue.
As with the TPA3116 chip boards, the DACs are cheap enough to buy one of each and I suggest you try that - more fun trying to decide which you prefer.
I ordered a 2nd dual chip board yesterday... What the hay!
I have a backup
It works. Wow!
