Tube in Preamp or Power amp?

Depends on your system (speakers) and the type of sound you desire. But, I can tell you that there are some pretty darn good tube and solid state pre-amps out there, so simply stating that a tube pre-amp is best is, well, not quite accurate. same for saying that a solid state amp is best coupled to a tube pre-amp. Borrow a few tube and solid state pre-amps and amps that you would be interested in, connect them to your system in your home and listen for yourself. My system currently has a tubed pre-amp, Audio Research REF 3 (would like a REF 5SE, but that isn't happening any time soon), coupled to two Mark Levinson 23.5 amps, driving Martin Logan Monolith III speakers with a Krell KSB balanced electronic crossover configured for my speakers and I am very happy. I have heard the new Audio Research REF 250 tube amps and if I could afford them I would get them immediately. They are on a very short list of the very best amps I have heard. Tube or solid state. And the REF 5 SE is one of the best pre-amps I have heard. So, depending on the sound of the setup, I could go either way. In my system, with the REF 3 driving the crossover and then subsequently driving the two 23.5 amps, this is as close as I'm getting to "there" without spending a ton more money, and contrary to what some may say, the 23.5s are still one of the best amps out there.

Elizabeth is incorrect about the dangers of modern tube amps although exaggerating to make some point isn't all that rare around here, but does damage credibility. Although exceptions exist, I've been using tube amps since 1966 with no fires or explosions, and she leaves her gear on all the time which is not only shamefully wasteful, it actually does increase the dange of fire in case of failure in her rig. And Bo...regarding my being an amateur, although I am not a gear salesman, I've been a successful professional musician and respected professional sound technician for over forty years, I currently work with some of the best musicians in the world, and I still don't think my opinion regarding hifi is any more valuable than anyone elses...I merely refuse to accept your incessant misinformation as fact.

It's ok that every person gives his own view. The question has not been answered. So before we can say anything you need to know which speakers he uses? Sound always will be a personal thing. It is Always about comparing to hear what you prefer most. First you need to compare different amps with your speaker to see what you like most. Same about how much money you want to spend on both power and pre amp. Sometimes the amount will give a better result with SS over tubes with the speakers he uses. Because sometimes you need more money to get good resuls with more powerful tube amps to drive the speakers you are using. Start asking questions to Solaris4ever before you give all this different opinions.

First I will say that I like tubes and think they are way cool and can sound really good.

Then I will say my approach, FBOFW, is keep tubes to a minimum because there is additional work involved to care for tube gear properly and there are many ways to get good sound without them as well.

If one will be using tubes, two ways to keep them to a minimum accordingly:

1) use in pre-amp only
2) use in amp and use fairly hi efficiency and tube friendly (higher impedance, not 4 ohm) speakers to keep # of tubes, size cost and complexity to a minimum.

Tubes wear over time and are more noise prone than SS. They also will tend to go bad completely more often.

There is something to be said for keeping things simple and relatively maintenance free. I shoot for that but I still run 6 tubes in my arc pre-amp in my main rig. It sounds really good, but my preference would be for the same quality sound with no tubes to have to deal with. Its probably possible, but so far I have been able to live with just occasional tube related noise and issues without too much pain.

OR if you are one who just loves tubes and the more the merrier no mater what, just have at it! But expect more time and issues dealing with noise and other problems when tubes are not performing up to par compared to the alternative. Tubes tend to get HOT, so chance of fire has to be higher in general I would think, though chances of happening with gear in good working order that is properly cared for is probably not too great. Its a real issue though and worth some consideration. YMMV.

Wolf has been involved with music professionally since the 60s. Assuming it took him until the mid-80s for the fog in his head acquired in the 60s to clear and accordingly we should discount the first twenty years of his experience, he's still been at this a lot longer than never-ending infomercial guy from Holland.
