What are the best tube amps for Klipschorns?

In answer to your question: Wyetech.
Additional comment: Agree to consider warm tube preamp, would add to consider hybrid amps - Blue Circle, Butler, even Counterpoint/Alta Vista, et. al.

I can't imagine how a transistor amp could be preferred on a speaker like the Klipsch- unless one has never heard a decent tube amp! First off the Klipsch doesn't really play the bottom octave, so the idea that a tube amp would have less punch is irrelevant, not just because of the frequencies that are audible but also because the Klipsch is a very easy load for tube amps so there is no advantage that a transistor amp will have with 'current' *or* bandwidth.

Perhaps you might actually try a few of the better tube amps- Klipsch speakers certainly have the reputation that justifies a decent amp for them. Good quality output transformers are rated to 5Hz and a lower powered amp (under 50 watts) will have no trouble having bandwidth.

The idea that transistors play bass better than tubes is a myth from the bad old days- 2 or 3 decades ago. If you allow a story like that into your head you will miss a whole world of possibility.

At the risk of being accused of picking a fight with God, I respectfully disagree, Atmasphere. :-)

We have paired our Klipschorns with quite a few different amplifiers (Quicksilver, Audion, George Wright, McIntosh, Art Audio, etc.), both tube and SS. We happen to enjoy both. Yet there are distinct differences between them, particularly when it comes to the impact and definition of the bass, where SS has bested tubes every time. In addition, the SS lends a greater sense of speed and separation to the music, whereas tubes excel at humanizing tone. Does SS have the emotional impact that the tube amps do? No, not to my ear. On the other hand, while tubes/Klipschorns are distinctly more engaging during active listening, SS sounds remarkably more even and cohesive from anywhere outside the listening room, save perhaps a solo instrumentalist. When listening to Led Zeppelin, Frank Zappa, U2, or even big band, despite the fact that a 1W amp will drive the speakers to ear-bleeding volume level, the SS amp (we pair ours with a tube preamp) is much better at approaching lifelike dynamic heft than any tube amp I have tried, even 60W or better.

So it's settled...we need two systems!

You may want to consider the best of both worlds. An amp like the HK Citation II @ 60 wpc. It has solid state rectification with tube output. These amps give the great bass punch that you get from SS combined with the warm, revealing mids that you get with tubes. Good compromise choice.

No, its even simpler.. Top end and mids maybe should have low power tubes for best dimension, and Big bass drivers should have solid state.. This seperates power supplies, and frequency demands of the weak points on both technologies, well its not perfect, but as close as we can come with a little experimentation.. I will be running my full range hopefully in the next 2 weeks with Pure Class A tubes on the mids up, and my Bass Line arrays on 700 watts of Solid state... In order to get that type of power and control on woofers for about 100 hz down would seem that it is a waste of time, money, Heat and Dozens of tubes to do what a cheaper solid state can do to take full control of bass drive for no heat, very little money, and just as good of tone down low, pure reliability with plenty of impact.
