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

The Aleph-3 is the best amp I have ever owned.
Too bad I bought some Thiels and had to go to a bigger amp.I wish I would kept the amp and bought different speakers (for power only as I love my Thiels) Although this thread asks for CLASS A bias amps only.I would like to add,my Threshold A/B S/300 is a killer amp!
It drives my Thiels with ease,and then some.
