Overtubing? Danger?


I like the sound of tube amps. When I was a kid, my family had one of the huge music consoles and I was always in amazement when the back was removed for maintenance and a whole city of tubes was revealed. Plus, it sounded fat and rich.

Today, I am trying to recapture that sound, but I wonder. What does a signal from a CD transport, with tubes, sent to a pre-amp, with tubes, sending a signal to an amp, with tubes due to the sound? Is more tube better or is it overkill?

This is kind of a funny question. I generally worry about whether I have any transistors in my gear.

To answer your question, it depends on the gear. My feeling is that the fewest items needed in the signal path, that can get the job done well, is better than more items. Adding unnecessary items, whether they be tubes, or anything else, is not conducive to good sound.

If you are wondering if you should put tubes in your system to cover up the digital flaws, then maybe you should look at the source, and fix the problem where it begins.
As I understand, it is the inefficiency of tubes versus the efficiencies of transistors that give tubes that warm, human sound. Tubes add harmonics that transistors leave out. Am I right? Ok, if I am on the path. What happens when a component with tubes adds harmonic color, then passes it to another component that adds component color, then passes it on to another component that adds even more. Is it better to have only one add tube sound and all the rest of the components reproduce that efficiently? I hope I am making sense.
Well Matchstickman, If I count all the tubes in my system I come up with eighty four.

I cannot imagine substituting any for transistors. Fact is, my home theater began it's life as 100% solid state and evolved to all tube (at least everywhere possible).
Being that both Albert and myself are tube guys, you are going to get a "tube answer" from us.

I believe that "all tube" is the best way for sound quality in the majority of applications. You do not "ruin" any of the sound with tubes. A good tube amp or preamp will make the sound pass thru very clean. There is much less "grain" sound with a good tube amp. People with tube systems can hear if there is as few as one transistor in the signal path, because of the way it changes the sound. Once you start going into tubes, you will very quickly decide to eliminate all the transistors in the signal path.

Others will drastically disagree with me on this. I guess you just have to hear it to find out.
Some tubes may be in store for you...you aren't getting married! There are no truisms for any type of gear. A tube preamp or power amp CAN measure and sound very much like what we may consider a "solid state sound".

Then there are preamps and power amps that have that golden glow. Can you get to much "tube"?? I don't know about that...but no matter what you can get good or bad tonal balance. And it could be 100% solid state OR tube!

And it depends on what speakers you have as well as your room, then finally...your tastes.

Getting past that...there is certainly a connection with life via a tube system. And you can stick your toe in the water pretty easy via a hybrid product...or maybe just a tube CD or preamp.

It's funny...while I am typing this I am listening to an oldies radio station, and they are playing the theme song from James Bond "Goldfinger". Have not heard that one for a jillion years...but remember how I felt when I first saw the movie! When I hear my fave music on tube gear it's the same deal. How do you explain that feeling?
