Puppethead,
Welcome to the hideout.
Just to add to gonks thoughts ....
you will be hard pressed to find sonically better combo than the 990/7125 in a receiver.
Even in separates – you will have to spend some money (5K-10K) to step up from Outlaw products (990/ with either the 7125, 7500/7700 or mono amps)
If you decide on 990/7125 combo – you could bi-amp the Jamos.
I have not heard the Jamos personally
A couple more speakers ...check out rbh, Moraunt Short Avant or even Magnepan besides the ones mentioned by gonk.
Over in the 990 thread MarkBK just finished a personal shoot-out between the Arcam AVR300 and the 990/7125 combo. Good stuff.

Have fun digging around the forum. There is a wealth of knowledge to be had.
