Questions about Preamp Tubes

Hi,

I was thinking of buying a preamp (tube and SS). Will the tubes need constant replacement? If yes, then I would rather just use SS preamp to save myself the trouble/cost. My understanding is that it becomes very, very hard to differentiate between tube/SS in high-end products; however, is this the case in lower-end models? Will it still be the case in cheaper/older preamps by Audio Research and Conrad Johnson (those were the ones I was looking at)? Obviously I will try to try any preamp out if possible to test for synergy, but I don't want to consider tube preamps at all if they have the above problem.

Small signal tubes, like the 12AX7, etc.. do last considerably longer than tubes such as the 6L6 in most cases. I wouldn't worry about how long they last because they can go on for years. Small tubes are replaced more often because of defects rather than normal wear & tear.

Tube preamps, in my opinion do sound considerably better! Try and get one that's point to point wired but not 40+ years old. Look for basic models without tone controls and tonnage of bells & whistles. Old is OK if it's been refurbished.
