SET vs OTL

Its the amp design,construction as much as the output tube thats responcible for sound quality. Having owned over 10 -45 SET. Probly arround 25 others SET many OTL SS PP etc. I can say that I did not find 45-50 SET to be the best in anyway. I look at total design not just tubes used and make dam sure it matchs loudspeakers or you SET yourself up for falure which is what most 45 2a3 owners do. Wavac, MasterSound, PAD, John Hogan have owned these 300b amps and they sounded much better than my 45 SETs and I have owned most of the great 45 SET amps that get raved about. With SET match your loudspeakers to amp or forget about it. Would say the same about OTL designs.

I can't argue with any of the above as I've never heard any amps built around those output tubes. I've always been concerned about speaker matches - as per Atmasphere's observation. Personally, I love most of the 300B designs I've heard and some of the best sound (though maybe not best deep bass) I've achieved came from 300Bs with slightly lean speakers

The original Merlin VSM SE with the Carys was a great match. I remember having a turntable set-up guy -from a very, very high end dealer that carried only SS electronics at the time - install a new arm. When he was done and we listened to the system, his eyebrows literally
arched up. He was stunned.

My point is that a good 300B set up with appropriate speakers can be very satisfying. Strictly neutral sounding amps have never IMHO been any guarantee of good sound. The right amp with the right speaker has always been the trick for me. After reading these comments, I'm sure I'll check out some of the lower power SETs you guys are so enthused over.

Given a speaker can be driven by an SET amp of comparable build quality/design the 45, 50, 2A3, and PX-25 will outperform a 300B all day long, due mostly to superior linearity. Don't even mention the 845 and 211.

I've heard a boatload of these amps with appropriate speakers and I stand by my previous post.

Audiofeil,
"Don't even mention the 845 and 211."

Don't mention the 845 and 211 because they are more linear or less linear than the 300B?

The Merlin needs a little more power than most SETs can produce, if you really want to hear what the speaker or the SET is capable of. With that speaker, hands down an OTL will do better.
