Theoretically, which amplifier drives best, to low or medium listening levels, a ML hybrid (e.g. Spire, Summit, Montis, Expression etc.) (sensitivity: 91dB, Impedance: 0.8/20kHz);
a) An amplifier that doesn't double down, but delivers 300W/8Ohm, 430W/4Ohm, stable at 2Ohm loads (like the Mark Levinson 532H), or
b) An amplifier that delivers 135W/8Ohm, 270W/4Ohm, stable at 2Ohm loads (like the new Mark Levinson 5302)?

Notice that in both cases the amp manufacturer doesn't state exact output at 2Ohm, and doesn't say anything about <2Ohm loads. Actually, the 532H which I've been using for the last 5 years to drive my Spires, is stable with them. However, I am not happy with the reproduction of high frequencies, which seem to be faint and weak.

Comment: Traditionally high quality manufactures like Mark Levinson, Krell, Parasound, Electrocompaniet, Simaudio, PassLabbs etc. that used to manufacture power amplifiers that doubled output down from 8 to 2 Ohm, do not make new models with this specification. I think this is becoming a common issue to ML owners or future owners, who need to know the amp output in very low loads.

Should be fine either way. If I were choosing, I'd pick the doubler.

With that said, I prefer tubes these days. Right now, this week, I've got my Krell re-attached to the Expressions while I'm doing lots of testing and need to do a lot of turning on and off, and it's just not as life-like in the soundstage. Sounds great, and has a lot more top frequencies, but just doesn't sound as real. So with my tube amps set to Triode Mode and using KT-120 tubes the power is a little over 70 watts of euphoria at any volume, as high as you can stand.

There is a prominent "local" dealer, Abt Electronics - local but national, that is a Masterpiece Dealer and they highlight the ML room with Mark Levinson amps. Years ago they used to be a Krell dealer also, which is where I bought my Krell, but now it's all Levinson and McIntosh and they use both to drive the ML's.

assuming both amps operating within spec as advertised and no issues I doubt very much if you could tell the difference.
