Isn't Ultra has the same internals as regular with just additional upsampling chip? I used to own 2006 MicroDAC (regular), it was not bad paired with Transit and 24/96 SRC upsampling in foobar2000, guess that should have made it somehow closer to Ultra, but even with all that Stello DA100 directly out of USB was clearly superior, in fact I feel Pico's DAC is better than my old MicroDAC, as it is stepping on Stello's heels already, but I don't have it in my possession anymore to do A/B comparison, so take this assessment with the grain of salt.
