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?

Zaikesman, yes I was referring to instrument amplification and your point is well taken.

The more things change, the more they stay the same. What I am seeing here is simply a re-hashing of the old "measurements" argument that was totally de-bunked, and trashed over 20 years ago. The measurements do not reflect the sound of the equipment when it is used in real world applications. Yet people still cling to this dead horse. And it gives rise to these incorrect statements about tube colorations and distortion, in comparison to SS amps' colorations and distortions which are usually designed from the ground up to have great measured specs, but can't cut it as well in the listening room. Look, a cheap Yamaha reciever will measure out better than a Ongaku amp in the lab. Is there anyone who thinks that the Yamaha will sound better or be more truly accurate at reproducing music than the Ongaku? Puhleeeese. If measurements are your thing, then go out and buy a set of test instruments and hook your SS amp up to them and watch the meters move. If sound is your thing, then buy a good tube amp and hook it up to your speakers and enjoy music. If you think for one minute that those specification measurements are going to tell you anything about the real world capability of that amp, then you are sadly mistaken. Specs are a marketing scam, and that is all they are. I am very surprised that people on this board are still under the same misconceptions that were thrown out the window 20 years ago. The only spec I need to know is if the unit will turn on. The rest is done with the ears. By the way, the THD of this post was <.00000001%. Wanna buy it?

TWL, I think you are putting too much emphasis on Unsound's mentioning specs. Asa, as has been pointed out to you, there are a great number of tube users switching to Pass solid states, class A amps, and hybrid amps. The same can be made of ss users crossing paths with the former.

I am wondering what definition of "space" we are discussing. Coming from a science background, I can only envision a "formless waste."

If it is that all that pervasive thickness that clings to you like a muggy summer day I left behind when I switched to Pass from what I admit wasn't the last word in valve technology, than I don't miss it. If it is the sense of performance ambience that is delineated by location acoustics you want, then what you need is a transparent amp. Secondly, also bare in mind, to reach that end, the choice of speaker is even more important.

I'm partial to both ss and tube camps. I have found a way to harness both's positive attributes, leaving behind negatives. It works for me.

TWL, actually the Total Distortion of your post was 100%. I suppose you use those arguements with the judge for a speeding ticket. "Gee Mr. Judge, it didn't feel that fast, no matter what the instruments indicate".

Lighten up! Its just a discussion about why some people prefer Tubes over SS, not a personal attack.

Okay, I'm out of this thread. Go ahead and hug your measurements. The funny thing is that this argument was over and done with 20 years ago, and many of you haven't even caught on to that yet. I just hate to see people floundering around in the dark. Just in case you need an update, the news in 1980 was that specs don't tell the story. Nothing has changed about that since. I thought this was an audiophile site.
