Hi, I am Looking forward to buy Audio Note Cobra integrated with built-in DAC.
Audio Note’s description of the DAC:
“The digital coax inputs can accept signals up to 24-bit/176.4kHz (native bit-depth for the Philips TDA1543 D/A converter chip is 16bit, so anything above this is truncated down). The Optical SPDIF input can accept signals up to 24-bit/96kHz (see above). The USB input can accept up to 16-bit/48kHz.”
So I want to use an Allo DigiOne which is connected with LAN to the Roon Core. From the DigiOne I will go with Coax into the DAC of the Audio Note.
My question is, do I get a lossless signal-path with this combination or not? Do not want to use any DSP settings within Roon.
Thanks for help.
hello, no one here can help?
Question: Why would one buy a DAC with chips from 1991 and at the same time be concerned about lossless transport? You sure can get a lossless 16/44 with it…
From your description, and the Audio Note site, you should, if the S/PDIF coax input on the Audio Note is up to spec. But note that the path won’t be really lossless for 24 bit material, as the lowest-order 8 bits will be dropped. It’s unlikely that’s audible, but you should keep that in mind.
As @KMM asks, it seems a bit sad to use such a limited DAC with a fine tube amplifier (Audio Note is justly famous for their tube amps, transformers, and other parts). In your shoes, if committed to a multibit DAC, there are excellent options, both NOS and oversampling, from Schiit, Metrum, Sonnet, Soekris, Holo Audio (the ones I’ve owned or own) and others.

Hey @erho,
Thanks for posting on community! It’s great to see you engaged 
I’m sorry it took us this long to get back to you. We had hoped it was going to be much much sooner 
.
It looks like both @KMM and @Fernando_Pereira had very insightful comments. Is there anything we can help with?
yes, thx. the sound matters not the technic
