Have you considered a (low cost > sub $500) Jolida 302? I
know that your first post pointed out that you were looking for a Transistor vs
Tube amp but, A lot of the “full range” speaker users gravitate towards smaller
“tube” amps (you will get a better mellow but, robust) sound: Here is my 50Wpc
Jolida 302 running my (rather inefficient) 82Db Infinity Renaissance 80's w/
some major authority:

(Please listen on a system that will allow for the full
range sound to be reproduced > not iPods, trust me you will hear & feel
the difference)
One of these "small" Jolida amps (their simple and reliable) would run your whole (Fostex) system
w/ a lot of "punch" and clear sound!?!
I have a pair of audio research reference 300 mono blocks running in my "main" system but, I swear; this "little" Jolida (tucked in my guest room) sounds "damn" near as "clean & clear" as a system that cost 40x as much! You might want to take a look at them as a "cost saving" venture that will "future" proof your whole system?
They are not too small and quite heavy (50Lbs) but, leave a
rather small “foot print”; the sound is fantastic! -Davis
