    Re: Tubed Power Amplifiers. Are the disadvantages too great ?

    But there are a few mavericks out there that push the state of the art. One is pretty well known- Nelson Pass. And now that class D has been around a while, there appear to be a few players that are making amps that are better than the usual tripe- that have musical qualities. Nelson is applying engineering to make the amp work according to what we know about human hearing perceptual rules rather than designing the stuff to look good on paper. As a result he makes some of the more musical solid state amps around. IMO we need more of that.[/QUOTE]

    Atmasphere, Why Class D? I am sort of interested in class D. I bought that super inexpensive Allo Volt +D amp. It's dead quiet in my system. Not a sound from it or my speakers. Every other Tube or class AB SS amp I have had hums on my rack and through my speakers. I am suspect its an issue with the output transformers picking up something and amplifying it. My little class D amp seems to have no transformers in it.

    Do your amps have an input transformer. I know they don't have output transformers. Are your amps more resistant to humming issues?

    Not sure anymore where this thread is heading...or maybe there's actually no longer any direction.

    Regardless, I think it's accurate to say that we have really excellent tube and SS amps today that can meet a wide set of customer's requirements for performance and create engaging musical experiences.

    The hum is probably due to poor grounding schemes in the prior designs. That sort of thing is very common in high end audio. We have direct-coupled inputs. Occasionally we also run into hum issues- but in dealing with them we often find that something in the system was defeating the grounding scheme. We support the balanced line standard- AES48, which is pretty specific about grounding.

    As to class D, initially it seemed about lower power consumption which it why its very practical in smartphones. But it can also be about quality if the designer recognizes what is important in the final design. The criteria are different, since class D lacks many of the traditional issues and instead has issues associated with switching. But if they are dealt with correctly the result can be quite musical.

    Re: Tubed Power Amplifiers. Are the disadvantages too great ?

    Although I have a slight preference for SS, sonics are the bottom line for me. If it sounds good, it is good. Doesn't matter whether it's tubes or SS. In January I'll be taking delivery of a Gryphon Diablo D300 for my downstairs primary listening room. But I also had the opportunity to audition a VAC 170i all tube integrated amp that I would be perfectly satisfied with. Outstanding amp. Beautifully built. I can easily see why some might prefer it to the D300. But my personal preference and the sound my ears liked most was the D300. Doesn't mean it was better than the VAC, just different. I'm just not sure I want to mess with tubes. But that's me and my particular application. YMMV.

    However, I definitely could see where I might want the VAC for a secondary system (my upstairs living room) and for a different sound. I might not be going through tubes as much since it would be a secondary listening room and not used as much as my primary listening room. My 2 cents.

    There is something in the tube sound for most music except electronic and electronic dance music. You just need solid state for that.
