Atmasphere, interesting that you suggested your M-60 for the Horning. 60 watts would certainly up the power in comparison to anything I've driven the Horing with thus far. Actually I would think the S-30 would be more than sufficient power for either the Aristoteles or the Eufrodite. By the way I always spend a great deal of time listening to the M-60 and CAR T1s at RMAF. Very impressive!
I also (naively) find it confounding when power equates more bass extension. I doubt I listen to very much music that goes below 40hz, Led Zeppelin doesn't get spun that often and even if it were I'd just be listening to Jimmy Page's acoustical tributes to Bert Jansch. So rather than thumping bass notes I would rather hear great bass articulation from the sound that I do enjoy.
Another puzzling thing for me is 11flat6 term: "euphoric", which I take for meaning exceedingly warm. When I attend a live performance of someone like jazz guitarist Jimmy Bruno and his Fender amp, I'm not hearing a resolving defined sound; rather the sound is euphoric (if my interpretation of this word is correct) and fusing. When I listen to a Bruno recording I want to hear a little heat and breath to emulate that Fender amp. I've heard a lot of amps render that sound sterile. Having said that, I'm not quite sure I want the same sound when listening to an un-miked acoustical guitar. From some of my previous posts you'll get a similar rant regarding my love for definition and dissipation of jazz piano notes. In my cramped, but too large listening room I have two sets of speakers and have up until recently owned more than one amp. If I'm not paying attention to what I'm listening to, and it's music that I like, then I know that the sound is dry and sterile and it's time to switch out components or blame it on the recording.
Here I go rambling again, but I think my initial post implied that theres no one solution depending on what we listen to and how varied it might be. I think we convince ourselves that where were at in the evolution of our sound systems is the end all be all, but for a curious person like myself I always have an insatiable urge to further experiment and entertain others opinions. I like the idea of a 2a3 PP or possibly throw another OTL amp at them (Although I dont like the Horning/Berning combo, but thats just my preference).
