Hi Rick,
Some of the music I listen to: Radiohead, Rufus (& Martha) Wainwright, Damien Rice, Frank Turner, Rachael Yamagata, Ani DiFranco, Eva Cassidy, Eddi Reader, Tom Waits, Massive Attack, Leadbelly.
The room is about 17 foot by 14 with the speakers along one of the shorter walls. Unfortunately there is a 50 inch plasma TV between the speakers as I can't have separate tv and music rooms.
Never really been convinced by cables. However, the speaker cables were the most expensive QED cables in Seven Oaks about 5 years ago.
I used only the maximum buffer setting when I first got the DAC about a year ago. However, recently changed back to no buffering and couldn't really hear the difference.
I am fortunate in that I can listen to music at quite loud volumes - we live in a detached house. However, would also like it to sound good at lower volumes when the kids are in bed.
This system sounds pretty good and as it is. However, I guess the bass could be described as a little understated and other systems I have heard had more of a "presence" if that makes sense?
Thanks for your time,
S
