Maybe problem of us,we think tas5631 same as TAS5630,only add LC low pass on it,the core same as tas5630,we think tas5630 sound will better than tas5631,of course it is ourself idea,maybe problem.

Pwm DSP Tas3308 or other chip suit for tas5631,but if you use adau1701 or adau1702 as dsp and use tas5630 as amp,we think sound will better.

We are develop one system like sunshine request,now in debuggind,but HDMI have not add.

the amp module have two tas5630 chip,we revised the tas5630 recommand circuit,in this module it can works at full power continued
2X600W/2ohm or 4x300w/4ohm.

The dsp chip is adau1701,so much functions of it ,we have use it 4years,some functions have not skilled yet.

I Understand what you mean. Instead of finding a way to eliminate the analogue conversion TI just through another (substandard) converter on into the chain for those who want to come in digital first(??!) Not what we want at all! We want what Tact does with direct digital to the amp and then using only that (plus adjustable setting for volume control) to drive the amp output and making the amp the one and only D/A converter in the chain, not multiple conversions!

You already have great ideas already. A friend of mine already asks for one with SPDIF input.

My suggestions:

Put USB port on back and add switch or knob on front to select between USB and analog. This way people who have it permanently connected to PC do not have to see USB cable all the time.

Add XLR or TRS input to use with professional audio equipment.

For product with DSP add digital out so one can stack many together to make as complex active speaker as they like.

You are looking good!

One thing many of us diy folks like is a high quality capacitor upgrade option and your amps. Have you thought about this?

Maybe one last advice-the speaker terminals on the picture you have provided are the worst possible and in my opinion shouldn´t be on any quality audio product- they break easily (the springs inside), they have weak contact and they are almost impossible to use with some bigger diameter cable. I will strongly suggest to use something of higher quality-see attachment.
By the way i was allready asking for the G 100 from my mail 3dlab@email.cz like two months ago but i have been told that i have to wait
