The closest approach: what amplification?


Ken Kessler titled his book on Quad "The closest approach" to summarize Quad's philosophy of producing a speaker that gets as close as possible to the reproduction of a live event. I have been wondering if there is a type of amplification that gets us closer to the real thing more than other types. I have met many audiophiles over the past few years, and what strikes me is how religious people can get about radically different types of amplification: some swear that there is nothing like small-power SET coupled with efficient speakers. Others believe that you don't have a serious system unless you use muscular SS amplifiers (e.g. 300 WPC). Others believe that powerful push-pull tube configurations are the best of both worlds. Finally, there is a small community of OTL aficionados that look at the rest of the world as if they don't know what music reproduction is all about.

Of course these people value different things. Some like imaging more than other things; others value transparency; others are crazy about huge soundstages; others seek warmth etc. And it is clear that some types of amplification are better for certain things and others are better for other things.

Now, let us consider simply the reproduction of a live event (not some specific, partial dimensions). In your experience, what type of amplification got you close to the real thing? Powerful SS, SET, OTL, powerful push-pull?

To try and answer your rephrased question, triode tube amplification has most often yielded the best result for me across a wide range of speakers, however, since it has also been a giant pain at the practical level, I have looked for alternatives. My Tact digital amp has its own limitations and weirdness, however, in its own, very cool and quiet way, it gets me as close to the music as the triodes, and holds out the hope of improvement. My full range electrostats require a good bit of power plus stability into a capacitive load.
Setting aside the speaker, and from a strict theoretical standpoint, an OTL design seems to make the most sense.

IMO
I can't speak to OTLs but in my experience, high power push-pull has the greatest potential for communicating the enthusiasm of a live event. There are many attributes coveted by audiophiles that have little bases in live music - precise imaging being one of the most obvious. On the other hand, live music presents tremendous dynamic contrasts compared with audio. Low powered amps like SETs tend not to fare too well in this department. And while powerful solid state designs are dynamic champs, there are just too many other areas in which they fall short.
