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?

KarlS, you need to try listening to a Berning ZOTL. One reviewer, when he was asked about the ZOTL he reviewed, said that it was the best SS amp he had ever heard. Of course it was a tube amp, but the point he was making was, that it had the beauty of a tube amp with the speed and woofer control of a SS amp. The Bernings are remarkable amps.
To further expand on the Berning bass performance I will say that the Berning zh270 amp has bass performance comparable to the best ss amps I have personally heard. With a stable 8 ohm load this amp will deliver full power down to 2hz and listening is believing. I have never heard any tube amp deliver the clarity, pitch definition and sense of real acoustic space in the low bass like this amp. It is comparable to the best ss in these areas if not offering the ultimate slam of a large ss amp. Another example of the converging of the two technologies.
I feel that a considerable cost upgrade was required to get a SS amp that I could live with. I eventually went with Accuphase. It has the so-called 'Accuphase Golden-Glow' sound, a smoothness and fullness similar to tubes, but with the power to rattle the walls. I currently drive it with an Air Tight tube preamp and I am quite pleased with the combo.
Dburdic, I agree with you about tube systems. I hear the tube amp. Some of the tube defenders call this continuous space. I call it glueon. I like black space. On the other hand, I have yet to hear, vinyl aside, an ss system sound pleasing. Like Tubegroover, I strive for a balance twixt the two. I use a transparent Pass X 150 for power, a Pass Aleph P for gentle switching; and a well tubed Jolida 100 controls the sound. As has been noted, solid state amp technology has progressed, so much so, that you won't hear any evil second order harmonics. Pass X and XA amps are foremost examples. Then again, the Pass amp can sound horrible if used in a poor sounding system. It is a slave to whatever is fed to it. I think we all understand that.
I would add Atma-sphere amps to this list. OTL amps that really "kick" at lower levels. My former amp (integrated) was an EAR 834. Great amp, about the same power as my new Atma-sphere MK60-2.2's, but what a difference in presentation! The EAR had the definate lush tube bloom, sweet but without the bass control and snap that the Atma-sphere has. The Atma-sphere OTL combines the warmth and liquidity of tubes with the punch and control of transistors, without that solid state "hash". (Please email me if you want more info on Atma-sphere equipment. I have no financial interest in this product line, I just know an affordable gem when I hear it!!!)
