We seem to have lost the original poster. My take on his post is that he
believes his amp -- Nakamichi AV-8 -- is tonally "bright" and he wants to
find speakers that are tonally "warm" to counteract this effect. So, when he
says "laid back" -- I think he's talking about tone, not necessarily
dynamics.
But, after doing some research, I have a hunch that the brightness is a room
problem.
I went to www.audioreview.com to read what Nakamichi AV-8 owners have to
say about the unit.
Not one owner in 37 reviews called the amp "bright."
Here are some of the comments --
"Very clean, warm sound."
"The sound is sooo warm."
"Clean, warm sound, decent power."
"Warm, clean sound."
"Has that Classic Nak warmth."
"Excellent, warm, full amplifier."

Not to beat a dead horse, but "WARM" *is* in the ear of the beholder, so the
original poster may be hearing the same amp as "BRIGHT" or it may be that
the brightness is coming from somewhere else in the chain -- like the room.
It'd be helpfull if we could get a description of his listening room.
