Congratulations!
This is great!
Most people with Extreme and DAVE prefer the offline upsampled PGGB files over the realtime upsampling the Mscaler does. I do too, although I don't have a DAVE permanently in my system anymore. The only issue is it does not work for streaming Tidal, Qobuz, etc.
Completely agree with
@jelt2359 ' s comment above!
To get the best out of the Taiko Extreme, it is highly recommended that you take advantage of the Taiko USB driver. I think it's a must with XDMS. Chord DAVE uses Amanero USB, which does some funky things. Without going into technical details, let me say that it defeats some of the principals Taiko is trying so hard to implement. Hence, the Taiko USB driver does not work with the Amanero in the DAVE DAC.
Adding an SRC.DX might be your best choice with the Chord DAVE. It's a passive device you insert between the Taiko Extreme and the DAVE. Connect it with a USB cable to the Taiko and then connect it to via dual BNC cables to the DAVE. Get yourself some good BNC cables... this will allow you to utilize the Taiko USB driver, because the Taiko USB card will be communicating with the SRC.DX rather than the Amanero on the DAVE.
Of course, ultimately you should just do an A/B comparison and decide for yourself. Feel free to send me a PM if you have any questions.
Also, if you use a Sean Jacobs DC4 for your DAVE, Sean is about to release a new (inexpensive) board for the DAVE that everyone seems to love so far.
