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
Threshold sa-1 or sa-2 mono bloc amps are still considered the best of class a sound today. They are just very tough to find.

Gryphon mono blocks DM-100. Excellent amps.Threshold Amps are too bright for my taste.
There are a number of folks on this site who own or are big fans of the Forte Model 4, which I thought was a great little amp when I heard it years ago. You might want to check the archives.
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...
