Older PURE CLASS-A Amplifiers


I am looking at some older Pure Class A amps and am curious as to are they as good as some newer amps like the Pass X150, and which ones are recommended, and have they been compared to each other anywhere? Thanks much for the recommendations.

I am considering the following PURE CLASS A amps:
Threshold T-50
Monarchy Audio SM-100 Monos
Monarchy Audio SM-70
Forte Model 4
tpk123
I should have put, that wanted to spend less than $1000, which is why I am looking at older gear. Thanks for the responses!! Keep em coming...
Consider checking out a Stax DA-80.
Pure Class A.
Runs hotter than hell.
You could fry an egg on it.
Sounds great.
It will be in your price range or below.
The Forte 4 IS a great amp and will cost you about 1/2 of what you wanted to spend, I think.
I'm pretty sure you can get the Monarchy SM70 and run it as a mono amp. Two of them run as mono blocks would be relatively inexpensive, and very good sounding.
