Solid state amp to replace my Audio Research Ref 150 amp


I have owned an Audio Research Ref. 150 for 4 years, but with tube changes and the heat, I'd like to find a solid state amp that would mate well with my Baby Nola speakers, as well as be 100% reliable and have the great sound my AR amp has given me. The AR amp was originally recommended by the Nola designer, Carl Marschiotta. 

My listening tastes primarily range in jazz, classical, roots music, and Americana such as Jason Isbell. I do like to rock the house occasionally, but I greatly value the finesse I get from the AR 150, as well as the solid bass and dimensionally my amp provides in my system.

I don't want to replace my Audio Research preamp and phono preamp, so I am wishing for a solid state power amp that will fulfill my amplifier hopes, work with my other AR pieces an continue to provide me the pleasure my Audio Research amp has given me.

 I would like to pay less than $8k on AudiogoN.

Comments and suggestions are appreciated.

I have a Plinius amp and was concerned about the heat factor as well. I can tell you that I have never had an issue with heat even in class A. I suppose it depends on the load it is driving. Maybe take a look at Jeff Rowland amps.
I've been happy with the Cary SA 200.2 solid state amp, which replaced a Cary tube amp. Running it with the Cary SLP98L pre. A nice combo IMHO.
Try a symphonic line amplifier.  Maybe used Boulder but for that budget might be a stretch.  
Surprised that nobody recommended McCormack.  My favorite solid state.  And won't break the bank. 
Hi Shaq:

Sanders Sound Systems makes the finest Audio Solid State Magtech Power amplifier I have had the pleasure to own in my 40+ years as an Audiophile.
Presently using it with a Audio Research REF-5 Line Source Tube Preamp and REF Phono 2 Phono Tube Preamp. Fantastic Combination.

A new one can be purchased Direct from Sander Sound Systems for $5500.00.
If you are luck you may be able to find a Used owned one on Audiogon
for $4000-$4500.  The Magtech will deliver close to 800 WPC.

Please do yourself a favor and check out Sanders Sound System White papers on the Magtech Stereo Amplifier.

 Yes I do own a pair of Mr Sanders Magtech Amplifiers.
Almost forgot: Check out The lifetime warranty to Original Owner.
