Then I'm glad I decided to get the i-20. At some point down the line, I may get an outboard DAC to see if there is any improvement.
Regarding my MF gear, I have the A300 as well as the A3cr power amp, and the a3cr is now on sale as it lost a close battle to UPA-1's. I think the main difference is in the highs. With the MF amps, the highs seem a little softer compared to the Emotiva. Emotiva brings just a little bit more sparkle. Also, the UPA-1s are dead silent, so that did it for me. But, I could easily live with the MF a3 powering my fronts.
