Are There Any Inherent Advantages to Class A amps?


All things being equal, power supply size, wpc into 2 ohms and everything else, Is a class A design inherently better than an A/B design? Disregarding the heat issue with class A amps, what makes them so desirable?

I'm saving my money for a pair of used serious monoblocs. I'm thinking a pair of used Pass X-600 monos or a pair of used Krell 750 monos. On the used market, the Krells are approx twice the cost of the Pass monos.

The Krells are pure class A, the Pass are class A for the first 160 watts, then they go to A/B.

Thanks Tripper. Those links are extremeley informative and they were very well written.

I believe Audiogon should have a glossary page. The links you provided are candidates for such a page.

The Krell is probobly pure class a for the first few watts or so. If your looking for true class a look into set amplification.
