NOS Tubes--Are they worth it? or accurate?


After doing considerable investigation, I question whether it is worth it to undertake the quest of finding NOS tubes. Just looking at the volumes of discussion on audioasylum about Amperex 6922's and how many of them don't sound that good, the fakes out there, the difficulty in confirming how much use the tubes have seen. It just seems like way too much to deal with.

I know many will say, buy from the reputable tube dealers, but at what cost? Is their inflated pricing worth investing into something that has a limited life and can quite probably never be replaced? I think that looking into current production tubes that sound good would make a lot more sense.

The other issue is that many of the amps and preamps we are using them in are were not designed around the sound of these NOS tubes. If you substitute another tube, I think you are drastically altering the sound from the designer's attempt towards his version of reality and accuracy to something that is totally unrelated to this man's intentions and work.

It seems that we then end up with a mish-mash of sonics that are tailored to an individual's preference and may be far, far removed from any accuracy at all.

Hi Saxo; interesting thread: Paragraph by paragraph:
1. I agree and prefer to not buy tubes from anyone except a reputable dealer, and am willing to pay the price-- some of which is for piece of mind.

2. I found a type of NOS tube that sounds great in my pre-amp, and it was worth it to me to then buy 3 full sets (6 tubes/set) at $150. per set. If I could find present production tubes that I liked as well, I would certainly purchase and enjoy them-- assuming an acceptable price.

3. As you are the tube component owner, you only have to please yourself. As long as the replacement tubes (new or NOS) are electrically compatible with your component, choose tubes that YOU like and don't be particularly concerned with what the designer was aiming for. Afterall, he was probably trying to please as many people as possible. Only you can decide what is pleasant to you.

4. The designers idea of sonic accuracy may not be the same as yours. Further, the designers tube component may sound different with your components/speakers/wires/room than it does in his design system. Also, you may choose to deviate from absolute sonic accuracy (whatever that is) and choose something that is more pleasant to you in your system.

Personally, I like a somewhat warm, timbrally rich, full bodied sound because that's the way music sounds to me (I don't like that big bloomy, euphonic sound that some tubes produce). But some like a leaner more detailed-- or other sonic presentation-- there's no accounting for taste! When a professional reviewer describes a component as "accurate", take it with a grain of salt IMO. Only you can decide what is accurate and pleasing to you. Cheers. Craig
