Hello, i have a Wyred 4 Sound DAC 2 DSDse (special edition).
And it only has DSD64 and DSD128. So, pretty sure that yours doesn’t have DSD256 or more
Never had trouble playing DSD 64 & 128 with Audirvana connected with USB.
Now that i want to had a little more low end bass to everything file and don’t care about DSD, i am connected with i2S and playing everything upsample with a plugin for more bass.
You may want to do some more homework before jumping into an upgrade… At the cost of the upgrade and lower, there are many DAC’s today that outperform the upgrade…
