Ultralinear vs. Triode vs. SET


I currently have a Rogue Cronus that I have been quite satisfied with, but I am intrigued with the possibility of a SET amplifier. From both a technical and sonic perspective, what are the differences between a tube amp with switchable ultralinear and triode mode vs. a true SET amplifier?

Hi phaelon,
No real disagreement actually, Droz said he wanted comparisions with his switchable PP tube amp and a "true SET"amp. If he wants to expand his options, a 300b PP amp would be a good way to go i.e. the beauty of DHT tube vs a pentode indirectly heated tube. Many opinions is what I`d expect on a open forum that`s all. Regarding speakers , yes theh`re some restrictions but Droz has a lot more choices available then some would lead him to believe. Zu, Tonian Labs, Coincident,Horning,Audio Note, Living Voice, you get the idea as the`re many more.On the other hand if he was basing a system around an inefficent speaker he would then have to deal with limiting the pool of amplifiers( always some compromise is`nt it). Phaelon you have the NAF amp from Italy correct? I`ve never heard one but love the look of them.

"I`ve never heard one but love the look of them."

Yeah Charles, that's the nice thing about the Italian stuff; if you don't like the sound, you can always put it on the mantle and call it art. :-)
HI Jefferybehr,

How can my statement be wrong? The speakers you mention may impress you. But me? How can you put those words into my mouth? I resent you trying.

And how do you know that excellent to you may be junk to me. Do not try to push me in that direction. I know what I like. And, I don't like SET's. Sorry. I don't even think they can be called hi fi.

Atmasphere, thank you very much for that clear and informative synopsis. Great stuff.
Some really excellent posts above!

I'd be interested in further comments that anyone might have on how much of the 45/2A3/300B "magic" tends to be sacrificed in well executed designs that use higher powered transmitting triodes, such as the 211 and 845. For push-pull as well as SET configurations, if possible.
