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

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.
Tpk123,

You mentioned "older" amps, but the two Monarchy amps that you mentioned are still current products.

You don't mention what speaker you will be using. The Monarchy Audio SM-70 or SM-70 Pro are only about 25-30 watts/channel in stereo mode. They jump up to 70 or 80 watts/channel in mono mode.

At their used price, the SM-70 or SM-70 Pro are EXCELLENT amps, if you can live with 25 watts/channel. Heck, I think you can get a single SM-70 for under $300-$350 used.

Enjoy,

The SM70 has been discontinued. The SM70Pro is still a current product. The SM100's were replaced by the Se100's. Monarchy is very slow to update their webpage. I was trying to purchase a second SM70 about two months ago. I called Monarchy and they informed me that it had been discountinued.
Andy Rappaport amp one, along with the Levinson ML-2 (when owned by the man, not the marketing machine)are both teriffic amps. The Rappaport sounds smoother and more dynamic to me. As an interesting side light, it was rumored that Rappaport was put out of business because of the law suits from people burning themselves on the outside of the amp. Now that's what I call class A. Realize that these beasts are now 30-40 years old and that nothing really kills electronic components like heat.
