Tube Equipment: Gimmick?


I recently had a mechanical engineer (who has no interest in audio equipment or the industry) express amazement when I told him about the high prices of tube gear. His amazement, he said, stemmed from the fact that tubes are antiquated gear, incapable of separating signals the way (what we call "solid state") equipment can.

In essence, he said tubes could never be as accurate as SS gear, even at the height of the technology's maturity. This seems substantiated by the high-dollar tube gear I've heard - many of the things that many here love so much about the "tube sound" are wonderful - but to my ears, not true to the recording, being either too "bloomy" in the vocal range or too "saturated" throughout, if that makes any sense.

I have limited experience with tubes, so my questions are: what is the attraction of tubes, and when we talk about SS gear, do we hit a point where the equipment is so resolving that it makes listening to music no fun? Hmmm..or maybe being *too* accurate is the reason folks turn from SS to tubes?

Thanks in advance for the thoughts!

JAX2: You are absolutely wrong about 8X10 vs 35mm:the 8x10 will give higher resolution, more pixels per square inch. You can blow up an 8X10 much,much larger than the best of the best 35mm. That is not true of pricing either, a Zone VII 8x10, costs much less than a premium Canon or Nikon. 35mm is a journalist's camera, an 8x10 is an artist's camera. The Nikon F received its kudos from the Vietnam War more than any other camera, and took off from there. Take an 8X10 picture, then take a 35mm picture, then blow it up to 8X10, absolutely no comparison, all things being equal.

As far as tubes vs ss are concerned(and I have both): in less than 2 weeks time I can tell that the tubes are less than perfect, they have changed the sound, and the sound is not getting better. So do you all change tubes every two weeks, I think not! So after two weeks what do you all do? And to boot not all the tubes degrade at the same rate, which is even more a problem. So how often do you change them, once ever 6 months or a year. I change mine
every 90 days. the difference between new and 90 days is very striking!
