@grannyring These are the same Gallos. I guess the class d amp, while smoother than my Parasound HCA1200ii in the midrange and definitly stronger in the bass, has some sort of irritation associated with it. I wouldn't be the first to complain.
The Dirac improvement is amazing, so much so I'm suprised more 2 ch people don't use some sort of RC (maybe their room treatments are that good). My unfiltered sound is mud, so panels and trap time maybe.
My cables are 10 gauge blue jeans cable with gold plated bananas. IC are something cheap but not the real thin garbage. I do us an MIT-Z deluxe outlet for filtering (did lower the noise floor) but no special power cords or fuses. Mains are 10ft apart and with listening position 9ft back. I could try getting closer to a rule of thirds 7/7/7 for the 20' room and pull the speakers closer together.
The Parasound should go back in to test for relief. Gallo 3.1's are known to be a bit thin in the midrange (MZ2 the rescue?), I guess that's why I'm after a different sound with the DI's and tubes. Trouble is I've heard PSB T3 ported speakers and while the midrange was glorious, the bass was lacking definition. Would have liked to plug up the ports in back but the covers were missing. Kind of goes along with sealed subs are faster and more musical or am I wrong?
