Amperex 6922 overkill?


I have an all Audio Note system with a MK2 Sig. Dac. The stock tubes are 6922 Soviek's.
Will the Amperex 6922,PQ,White Label,Gold Pins,U.S. or Holland (Joe's tube lore) be a overkill in this Dac?. Cost for these tubes,$400.00? Yes!. Any other tubes that will work as well?

Thanks,

Redster,

$400.00 is to much for any tube, i don't care what it is

Your gear at retail, $130,000, + ?????????????????????????

oh, i know this hobby can get very expensive, and i have spent a considerable amount on it, i can justify spending money on a beautiful piece of equipment, but it really bothers me, when people try to take advantage, and sell tweaks at excessive prices, or make false claims about the amount of performance enhancement
Have some experience with 6DJ8's and 6922's in my Audio research pre... tried the Sovtecs, Bugle Boys, Amperex PQ's both USA and Holland, Amperex Pinched Waist, Telefunken CCA's Chinese 6DJ8's, Siemens and Halske 6922 Cca's amd a few others..... They all sound different .. quite different. $400 for PQ's is a pure rip. The most expensive NOS 6922's out there (EBAY) are the Telefunken and Siemens and Halske CCa's. A matched pair of Siemens and Halske CCa's NOS NIB just went a bit over $210 last week + a few $ shipping. Beauty of eBay is buy, try, sell until you get to buy try keep. The right tube will be like a 5X over equipment upgrade. .. a true eye opener.

How do you avoid the, seemingly endless stream, of rip-off artists on ebay?
PLEASE DON"T ENCOURAGE THESE JERKS THAT SELL TUBES FOR INSANE PRICES. If no one pays that kind of money- the price will fall.
My second beef is with the companies who almost invariably use the worst tube around in current production (Sovteks) for multi thousand dollar pieces of gear. They are very cheap tubes but There are current production tubes which are better and only cost a few dollars more.How cheap can you be! I can see why it would be impossible to use NOS tubes but the consistent use of Sovtek tubes is absurd how are they voicing their products, don't they realize that they are damaging their reputations. It requires you to roll the tube. This has happened to me on 3 occasions.
