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
A shortlist of the amplifiers you are looking for:

Classe DR-3B or DR-3 VHC (very high current)
Bedini 25/25 under serial number 100 -- these were the real 25's -- not the later and cheaper Japanese version, as John likes to call them.

Levinson ML-2's
Electro Research A75 John Iverson's first real amplifier
Krell KSA-50
Threshold SA-3
Here's to keeping the thread alive. Good for the search engine and anyone looking for good old class A amps.

The smaller Bedini's like the 45/45 and 25/25 are underated. I have a 45 that puts out sweet music to my Maggie 3.6's.

Jimmyblues, my 45/45 has a less than 100 ser #. When I spoke to John about it and mentioned I liked SET amps, he said mine was single ended and no wonder I liked it so much. Is this what you meant by the "real Bedini"?
Hello,

Is it necessary to change the caps after many years of intensive use on a Classe Audio DR3B? What kind of caps am I supposed to buy?

threshold sa3, or any ot the pass aleph amps, if they have enough can power for you. one of the biggest secrets in hifi is that some of these older amps not only compete with the new stuff, they are actually much better than what is out there today. goodluck chris
