Any idea to develop a DSP with a better ADC and DAC? The same ADAU1701 with a different codec should suffice.
cheers.
Glad to see you are making progress on these...
I am currently finding your AliExpress store "closed":
http://3eaudio.aliexpress.com/
but I can access individual item listings from your web site, for example here using the "Buy Now" button:

Which one should potential shoppers use?
A lot of us are looking for a DIY plate amp with DSP to rival the the FusionAmps. Vendors using the 1701 are doing that for the integrated ADC/DAC, upping the ante with external converters makes more sense to use the likes of 1452 and enable bass management / room correction with deep FIRs
I have the older 3E Audio amp without PFFB and it sounds great driving a variety of speakers. I’m hoping the new version is even better but I won’t know for sure til it arrives in a month or so.
It's not 3e audio, a lot of Ali is blocked for Germany. Several other vendors and parts I've bought before are no longer available, unless I use VPN. And even then, you can't select shipping to Germany.
I suspect it has to do with the VAT requirement - Ali doesn't ship anything, but has to collect and register all transactions with the German office. And since Ali doesn't seem to even generate the invoices for its sellers, I had several cases where I get an invoice in the package that doesn't reflect the VAT that Ali collected. And I have to pay it again, because the German office doesn't have the transaction in their system.
