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

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.

Look for a Bedini 25/25. They go for around $450-600 on the used market. John Bedini also will rebuild them for around $400. Lucious midrange! Your speakers will need to be at least 89db efficiency if you want to listen at higher volume.

Swamp - The pure class A 50 watt version or the 100 watt A/B version?

Levinson made a pair of very nice class A amps, monoblocks, rated at 25 per channel into 8 ohms....and 50 into 4...and 100 into 2...and 200 into 1..and 400 into 0.5..think they were the ML2 but not sure...one of them is at least as large as the stereo 100wpc 27.5. If a pair ever pops up for sale I'd give them serious consideration; they'll drive anything around probably.

Cut down on your heating bills, too.

Ever consider a tube hybrid like Lazarus H-1A?
