Help with Speaker Selection


My room is 20x20 with a ceiling that slopes from 8 feet on the sides to 16 feet in the center. The system is ARC 150.2, Naim CD 3.5, Sugden pre-amp and speakers Linn Keilidh.

One side of the room has 8 foot high shelving upon which the speakers sit. So speaker placement remains less than ideal.

I play rock and roll mostly. Any part of the system can be replaced but I have always enjoyed the ARC sound.

Will entertain any suggestion.

Thanks to all for their comments.

"One side of the room has 8 foot high shelving upon which the speakers sit.”

I’m not sure that I have an accurate picture in my mind, but the speaker setup, that I’m perceiving, looks like a bigger issue than the speakers themselves.
The older Linn's can sound pretty flat in the wrong set up and definitely is not a rock and roll speaker.

The placement is not clear to me, but assuming it's not behind the sofa or something, you might look at Spendor, Pro-ac or Harbeth. All have that great mid-range and top end, with manageable bass and will definitely liven things up.
Thanks for the responses. Meriwan : you have summed up the sound perfectly with the word flat.
Phaelon: the room has a cathedral ceiling with a "wall unit" that's 8 feet high. Above the center of the wall unit the ceiling peaks at roughly 18 feet. The speakers need to be placed on top of this wall unit.
