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?

On Pass. I like it: had a 30 for about a year, and have recommended it to some people in the past. Ono was nice, etc. and were very similar in sound. Like it more than almost all other SS.

Yes, the SE topology, assuming that's the factor, does make Pass more "realistic" in terms of objective criteria and more musical (meaning: catalyzes seeping into the music and receptive state of listening) more than many SS units (I also have recommended to people the Lamm 1.1 hybrids for the same reasons).

With that said, the Pass units suffer from some of the same problems. Source projection contains more air, but leading transient still posseses a discernible "dryness" which increases in obviousness as energy increases and one approaches boundary between source and space (hence, still delineating that dichotomy). Power handling can help (with its own trade-offs) but not to great degree IMHO. The air around sources, in fact, seems more pressurized, but still dissipates as you move away from sources and particlarly in the furthest depth field. Space has tendancy towards sterility rather than "aliveness" in most circumstances (you can tip the tendancy a bit with component matching, so Pass has more flexibility in this regard, but the wall is still there on spatial performance).

Nice stuff, better than the rest, I like it more than mushy euphonic tube gear much of the time, but still not close in these respects. I'd go for a Lamm 1.1 before Pass.
Hello Detlof,
"Perhaps it is the ambient noise of a life event , which I miss in classical CDs. Instead of blackness, I expect to hear those subtle cues, which tell me of the size of the hall, those reverbs from the side-, or backwalls, which simply are not there"

I have "that" what you've missed!...on my system. They are all there!!! And they are in CD's format.:-)

Well here you have it, Audiogon meets the philosophy majors. I'm going home to have a can of my favorite beverage, or maybe a bottle, or maybe a can or maybe I'll pour the contents of the can in the bottle.
Jetter, you can also pilosophise with beer, sometimes even better and deeper. There is no contradiction there. 6chac, congratulations on your system. Which CD's do you refer to, which can really do this? Very curious... Cheers,
Hello Detlof, thanks, quite a few, but just to name one, the CD is Telarc/Mozart Requiem. That same CD was dull, opague, compress on my old system which I'd sold in 1992. Check my answers in other treads.
