high power tube amps vs ss

"My questions is: is there anything to be gained by switching to these higher power tube amps over ss amps?"

Maybe or not. It would all depend on what you specifically are shooting for and how well what you have meets your needs or not.

I do not consider Dynaudio speakers and tube amps to be a natural match by design in general, and would not do that without hearing first but that's not to say you might not find something to like there if you heard it.

Agreed- in spades!

I would venture to guess that Al, but especially Ralph believe it's not possible to arrive at life-like sound without tubes given some of their prior posts. To that end I would like very much for either/both to cite some tube amps that are as fast as any ss amps they've heard so far. Imo, you can't get there without serious speed in an amp. For me it's 'the' most important factor. I really don't care what else it does well or poorly (within reason). And I don't care about published specs.

Csontos I would venture that the Atma-sphere amps, which I have heard in several unfamiliar systems over the years and in my experience the Berning zh series amps are as fast and transparent as any ss amps I am familiar with. Check out Berning's website for the numerous reviews of these amps to get an idea of their performance characteristics.

I have owned and been listening to the Berning zh270 for 11 years and the comments you have made above regarding tube amps in general are true in many instances but certainly not all. This amplifier rivals any ss amp I've listened to with reference to transient attack, pitch definition and bass control.

Hi Peter,

No, I for one would certainly not make any such claim. In part because my listening experience with solid state amps during the past decade or two has been minimal. Prior experience led me in the direction of tubes, with which I've been very happy, and in recent times I've simply had no interest in high end solid state. And my speaker preferences have always tended to be in the direction of those having impedance characteristics that are benign and tube-friendly.

For examples of tube amps that are "fast," for starters consider Ralph's OTL amps. Although I haven't had the pleasure of hearing any of them, by all accounts I've ever seen they have that characteristic in spades.

And among tube amps having transformer coupled outputs, my VAC Renaissance 70/70 Mk III certainly doesn't disappoint. While I realize that you "don't care about published specs," I'll mention that they are rated as being down only 0.5 db at 90 kHz on a small signal basis, and at 58 kHz at full power. At -3 db those ratings are 103 kHz and 85 kHz, respectively. Not very different than the very highly regarded Pass XA.5 series solid state amps, which are rated to 100 kHz (with no specification of power level or how many db down that is based on).

Yes, I know, a few solid state amps, such as those made by Spectral, go out to 1 or 2 MHz or more, but whether or not that is overkill, and whether or not it may even be sonically counter-productive, are certainly debatable.

As a point of reference, I'll add that I frequently compare listening results between my amp + speakers and my Stax electrostatic headphones + Stax solid state headphone amp. I doubt that anyone would ever accuse the Stax components of being "slow," yet I am not disappointed with the "speed" of the amp + speaker combination.

Tubegroover, thank you most kindly for your expression of appreciation.

Best regards,
