''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' From the first page of USBridgeSig manual: "USBridgeSig cpu is RaspberryPi CM3+ Lite Module. The CM3+ Compute Module 3+ contains the guts of a RaspberryPi 3Model B+" ... so the HDMI is a MONITOR OUT port.

Manual..... first time I've seen it, thanks.
Great piece of kit non the less, guess I'll have to go for plan B.
Amazon cloud drive .....Hmmmmmmmmmmmmm. POS.
Amazon Drive
TPA3255 AMP
I am making good progress but its a complicated design
1. PSU is a SMPS LL Zero V crossing at 225W with 2uV or less on 50V. PCB will be received in 3 weeks for testing
2. Front end (XLR and RCA) , we have designed from scratch, using FDA for very good CMRR rejection and used hi end opamps
3. TPA3255 itself its PBTL
Our target is 0.0005 THD+N at 1Khz and 0.002% at 6.67Khz
We hope to have it ready by September

Awesome!! I'll wait.
BTW, is there any smart way I can put few Katana together to form an active X-over + duplicate-channels (route), like Piano 2.1? I am planning my active x-over speakers.
Thanks again.
Thank you. I'm running 64 bit Ubuntu 20.04 on the PI4 and I'd like to try it in the USBridge Signature as well.
Just a few announcements :
Nirvana and Rev will be available to order this month.... as you know I have been working a lot on both (especially Nirvana ) and they are finally ready. Rev Dac is sounding very, very good. Page will be up before 25 of May
Allo amp 110W ...I am on pcb rev 2. Already I am beating by far the EVM from TI.However my goal is to reach the THD+N of all the big boys on the block (Neurochrome , Benchmark AHB2). I hope not to equal but to very as close as possible giving the dead time inherent to class d) . This amp will have XLR and RCA inputs and another goal is to have CMRR of more than 65db.. still my LLC smps is not ready .
I am also testing a new DAC with a complete new IC for RPI4 , but still have some work to do. Give me 2 weeks before asking questions.

Great news! I've been holding off on upgrading hardware for my Volumio streamer until I see what Allo comes out with. Any ballpark for the prices on the Nirvana and Rev?
Do you think you can get a Revolution to Judy for the June 4th Volumio SoundCheck in Hamburg? That would be a great debut for the DAC if it performs as well against the other DACS as it sounds like it should.
