Hi - you are correct. I must have misunderstood what the dealer told me. He may have meant each pair.
I'm being quoted a current price of $1,950 for the pair between the exchange rate (which is constantly changing so they round up the number to pad for the changes) shipping, customs, etc.
While they are fantastic tubes for sure, $2K is very steep.
The ratio I quoted them becomes the difference between $250 for the pair vs. $2,000. So it's about 60% of the perforce for about 1/9th the price.
I have been asking the same question lately because the problem with tubes and NOS tubes vs new PSVANE tubes or other modern tubes is that people have a vested interest in keeping their NOS tubes valued very highly - dealers especially.
If a guy is sitting on 10 NOS WE tubes valued at $4,000 a pop, and let's say PSVANE comes out with a tube that is as good or better for $300, then that would be a real tough admission for the guy/dealer sitting on those NOS tubes. If word got around and other people admitted the same things, then those $4000 tubes would drop to $400.
And here's the thing - when I have asked this question about a given PSVANE tube, I am not getting someone with direct experience. They are just taking it as a given that the NOS tube must be better because they read it on a forum or from owners of said $4,000 tube. And some of them may do a "comparison" but of course their $4k tube is best because man they're going to want to get rid of the buggers. How will you sell your $4k tube if you just admitted that a $300 tube sounds better? So no - you may admit that once you get rid of all the $4k tubes.
On YouTube, I watched a fellow buy some PSVANE KT88s and preamp tubes, and he wound up admitting that they trounced all of his NOS Mullards.
Now, people might say they are less reliable, but when you are paying 1/10th the price, it may be worth the risk. Maybe the $4k tube lasts 24,000 hours, and the 1/10th the price Chinese tube that sounds just as good (setting aside that previously mentioned bias) lasts 8000 hours. Well, 3 sets of these are still 3/10ths the price.
Like most things, each person has to decide on their risk tolerance - it's not like an amp or speaker that breaks - you can get it repaired - when the tube blows up, it's gone. 100% of your money is poof. With a car, you buy a warranty to protect your investment, or you decide to keep the money aside and use it for the repair down the line that may not come. You have to decide what sort of risk you're willing to take. And that $4k tube can go poof at any time.
Of course, the other factor is how much money you can lose and not be bothered. I watch a Watch YouTube channel, and he advises that you should only buy a watch you can afford to lose or have stolen and not be bothered - if you are spending $10k on a Rolex and you only make $50k a year, you might be devastated if it gets stolen, breaks, etc. If you buy a nice $600 Tissot that is Swiss-made made etc, you are still getting a very good quality watch, but if it gets stolen or breaks - yeah it will suck but it's not the end of the world.
There are, of course, many people, likely on this forum, who can afford to buy a $10,000 Rolex every single day and wear it once and put it in a closet never to be seen again. So a $4,000 tube - meh - why wouldn't you buy a dozen?
