I have it packed up and am shipping it. Robert won't respond to me or post anything on the forum any more, so @dinglehoser had to get the address for me. 50/50 shot I get it back to follow up with comparative measurements. And I'd guess 100% that Robert won't let one of these into the hands of another competent reviewer...

It occurred to me that someone could make a little money modifying these units to get the performance into something reasonable.

Thanks. In another forum he is claiming to be looking for the owner to tell him what to do. So I had to remind him that you have it and are waiting for him to respond per his own proposed process. He had a chance to handle this well but he is doing the exact opposite....

To be fair, I got busy and forgot to email him back with my address/instructions. So he was legitimately waiting for me.

A better shot of the chip (it looks ground off in the shot above- just the angle)

WTF is it? What a useless non-thread OMG =))

It's just a random picture thread. Pic above is an assembled, ready to attach power, stereo amplifier based on a TPA-3110 complete with a Bluetooth 4.0 transceiver onboard all for AU$7.16.

Crazy value for a bluetooth speaker build. :)
