The room has the usual wallboard walls and ceiling. I didn't mention that aside of the 17x18 ft room, there is an offshoot, an "L" that is 10 x 16 with 8 ft ceiling. the whole space is kind of a work out/multi use/storage area. The main part has only furniture around the edges; cd rack, big bluray/LP rack, computer desk, treadmill. But I'm just trying for a little more air in the sound. There is nothing between the listening chair and the system, about 9-10 feet.
Perhaps as several have said, the P7 or A21 are not at fault. I'll try the Pioneer cd player and maybe swap out the cables for some cheap fine strand copper. I was going to sell the P7, but it looks like I'd need to either increase the budget by a fair bit or go with tubes. And I'm not interested in tubes either.
