6922 recommendations for ARC PH7

Hi folks,

Looking to roll the tubes in my Audio Research PH7 phono pre. Looking for a recommendation for a 6299 that will extend the top end, midrange and give me a little more airiness without sacrificing the bottom end (Sorta what we are all looking for right lol) 

the  tubes I’m currently using are 4 Electro-Harmonix which sound good but they are a little laid back on the top. Very neutral sound which is a good thing, but want to try something new. My main room is not a very lively room as it is. However after testing the ARC in my living room system which is much more lively room I still am not getting the result I’m after. Dont get me wrong. Not complaining about the sound of the pre at all. I have been wanting to roll the tubes in this piece for some time now if not more than to just experiment with. Just got the itch to try something new. 
Thanks 

-Keith

I would never let go of my Steelhead. 
Are there better? Without a doubt. Is there anything more enjoyable in my system? I don't think so.

Back in the day, when the 6922 was in flower, there was an electronics company that made the best equipment in the world, by a long shot. That was Hewlett Packard, making the test equipment that put the men on the moon.

To run the very best test equipment required the quietest, most linear tubes obtainable. H/P did this by selecting tubes from manufacturers like Amperex and Telefunken, and charging the earth for their selected tubes. Stories back in the day told of co-op students testing a box of 144 tubes like Amperex SQ 6922's, putting the H/P stencil on 3 or so, and putting the rest in the dumpster.

But no-one remembers these stories now, or why they were credible. Bottom line is this: H/P branded tubes command no premium, in spite of being the best in the world, period. The very best were selected by Telefunken for H/P to H/P standards.

I have a sleeve of them, three still with the original Telefunken AND H/P seals. And you can't have 'em.

I would recommend the valvo 6922 6dj8 tubes from the fifties they are my holy grail of 6922 tubes and they are made to a higher standard than all the other variants. They sound absolutely like real music.

Interesting comments since I work for HP. Been there since 1996 😀. Yeah Bill and Dave did it right in regards to everything in those days. Can’t argue that. However if you want to unload those tubes let me know.
