To tube or not to tube...

I'm interested in upgrading my preamp and have been considering going to a tubed preamp coupled with SS power amp. I hesitate because of the reliability factor. You see, I grew up in the era of tube television sets, so it was a periodic chore to unplug all the tubes from the TV and haul 'em down to the local drugstore's tube tester. We'd wind up replacing a handful of tubes, and then be amazed at how much better the picture and sound was. A year later the drill would repeat. What's the situation with tubed preamps? I see a lot of discussion about trying this brand of tube or the other... I'm wondering how much of that "improvement" is due simply to replacement of weak tubes with fresh ones. What kind of life can one expect from the tubes in a tubed preamp? How much does the sound deteriorate over time as the tubes wear out? Are tubed preamps intended only for those who want and like to fiddle with the innards of their equipment?

I purchased a Herron audio Phono Pre, and it is not tweaky. People tell me the tubes should last for years. Keith Herron is very specific about not playing with the tubes he choses. I am very happy with the sound of this unit. It does not sound "tubey", and it is detailed. On the other hand it can bring something avilable in solid state only in very expensive equipment.

I agree the tube changing in some gear can bring different and sometimes better sound. For most pre amps tube life is longer than for amplifiers.

For tube equipment that sounds almost, but not quite, like solid state try BAT.
