Same feeling I get after returning from auditioning loudspeakers. It is most likely because we have optimized our system and also taken great pains to place the loudspeakers in the optimal spot.
Is the smearing of the notes due to flabby bass? I noted that during the demo at AXPONA this year. Maybe it was the room. But in the demo last week, the bass was better controlled than that at AXPONA.
I just keep coming back to your system. Can you please describe your experience with these loudspeakers? I see you have some formidable gear to go with the ProAcs. My room is so similar to yours (15 X 18 X 8). Did you hear the D48Rs, by any chance?
Very good setup. I just came back from auditioning the D30RS. They were pretty good sounding. But for some reason I thought they sounded a little darker. What other loudspeakers did you listen before settling down on the D30RS?
