@chocaholic Thanks for pointing out the original question. I agree that it seems counter productive to use Bluetooth. I know that you can listen to Qobuz and Tidal through the BluOS app, but I think you can only stream mqa through the BleOS app but need to go to the Tidal app to get flac level streaming, and I thought the only way to connect it to the Vault was through Bluetooth. But maybe there is a wired option?
I just read a bit about the Denefrips you suggested and it sound like a great addition to my system. I've been looking for a new DAC but haven't found the right one yet. BTW, what Revel speakers do you have. I had the Revel F208 and recently got the Studio 2. I also have the Niagara power conditioner instead of the Teddy.
