I have some ECC802S or ECC801S can't remember and have to wait a while until I am reunited with my tube collection. In any event there wasn't that huge world of difference between then and other high quality NOS types in the specific application I used them in. You say money is no object but finding the genuine article real McCoy ECC803S is fraught with difficulty. There are so many fakes floating around and relabled reclassified "S"s regular Old Stock tubes that are being dealt.
The cost is clearly rediculous no matter how wealthy you may be. It is simply obscene. However even if you are in a position to buy them I doubt they will live up to the hype and expectation. I would just get some well screened tubes from a really honest known dealer. You will be happy just to get truly good tubes What if you don't like them ? As a private seller you will never get near the price you paid.
