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?

Liquid(ity): nice words; the pleasant, natural flow of transient notes, sounds, without the warning telling lights of a change in course of the music.
That's typical of many tubes, but also of some ss. In these cases, we're happy listening and I don't think we actually notice the paarticulars of the reproduction because the music is too involving.
I'm referring to the usual shortcomings-- tubes' bass, the ss's mid, the tubes high extension vs. the ss, the "ear-friendly" (but usually limited) upper register of tube vs. ss...
I now have ss amps that allow me to forget my old OTL and my little Jadis. However, my ss configuration is in a different class altogether: wide-bandwidth (whereas my tubes were "normal bandwidth", at best). They have enormous driving power in class A topology (a Goliath situation vs my little tubes). And yet, it's only now that my musical ear -- as opposed to the critical ear -- is happy(ier). Morale (mine): a good ss offers precision, control, power, extension, and electricity bills worthy of a seasoned audiophile -- but unless you can spend mega$ on ss, the musicality will always be a little wanting, hidden somewhere... Bottom line is: given a medium budget, select carefully for a good tube. If necessary, tweak it.

On a side note: Scintilla. (yrs ago) I remember someone was trying to make his pair play music with a pair of Electro 50. These, while great, couldn't move the Scintillas beyond whispering level... they kept blowing fuses. All we wanted was to LISTEN to them so we looked around for a big tube, thinking that was a safe proposition -- but couldn't find anything on loan bigger than EAR 519 (i.e. mine, at the time). Those couldn't go very far either. Finally, a dealer consented to experiment with us and bring over 300 pds worth of amps (an old Symphonic Line model called Kraft 400A). These did it: we got the Scintilla scintillating, as it were.
For once transistors did it -- but the story is for Muralman1's benefit: not easy to drive Scintillas. Duettas were a piece of cake by comparison!
