Tubes Do It -- Transistors Don't.


I never thought transistor amps could hold a candle to tube amps. They just never seem to get the "wholeness of the sound of an instrument" quite right. SS doesn't allow an instrument (brass, especially) to "bloom" out in the air, forming a real body of an instrument. Rather, it sounds like a facsimile; a somewhat truncated, stripped version of the real thing. Kind of like taking 3D down to 2-1/2D.

I also hear differences in the actual space the instruments are playing in. With tubes, the space appears continuous, with each instrument occupying a believable part in that space. With SS, the space seems segmented, darker, and less continuous, with instruments somewhat disconnected from each other, almost as if they were panned in with a mixer. I won't claim this to be an accurate description, but I find it hard to describe these phenomena.

There is also the issue of interest -- SS doesn't excite me or maintain my interest. It sounds boring. Something is missing.

Yet, a tube friend of mine recently heard a Pass X-350 amp and thought it sounded great, and better in many ways than his Mac MC-2000 on his Nautilus 800 Signatures. I was shocked to hear this from him. I wasn't present for this comparison, and the Pass is now back at the dealer.

Tubes vs. SS is an endless debate, as has been seen in these forums. I haven't had any of the top solid state choices in my system, so I can't say how they fare compared to tubes. The best SS amp I had was a McCormack DNA-1 Rev. A, but it still didn't sound like my tube amps, VT-100 Mk II & Cary V-12.

Have any of you have tried SS amps that provided these qualities I describe in tubes? Or, did you also find that you couldn't get these qualities from a SS amp?

There is no doubt that tubes come in various flavors and colors, some of which are quite nice. Some are really awful, I'll leave it to you to discern. Imho, for little money you can get a really *nice* sounding amplifier using tubes, one that gives the impression of "musicality" and "smoothness." So, that is all good.

To get a similar result from solid state, imho (again), you need to go an "extra mile" or so to get certain things right, or else you end up with a sound that personally I do not like at all. Unfortunately, a *great number* of manufacturers seem to either have or like that sound...

What I think is needed can be seen on my site in either the SE Mosfet amp design, or better still in the full out Symphony No.1 design.

Having said that, I admit that I *prefer* the sound of a very high quality, high power triode amp on my ESLs over the arguably more accurate and cleaner Mosfet monster(s). However on other systems, there is no horse race at all. And for bass, tubes are definitely on the short end of the stick.

So, the answer is: use the right devices for the right applications. (often that means bi-tri-quad amp'd set ups)
