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 was blessed, we had 5 zip codes and a lot of frequent flier miles over the globe- took some risks and had a wonderful career.

I think the wine analogy is spot on, we serve DAVIS Family as our “ house “ Red. IF the kind posters of this thread find themselves in So Cal or Seattle, stop by with tubes to roil !!!

finally, I don’t disagree that hot ridding a circuit with high end parts can yield stunning results.... just make sure the signal in that circuit can form those big capacitors....

Ya, I spent thirty great years at Boeing... we did have an affinity for HP and Tektronix... had our own Cray and cert / calibration labs.., etc
do some research on RAM tube testing/matching... for grading current production I doubt anyone affordable does better...
maybe Andy at Vintage Tube... but he “ hates “
Russian tubes...

I really enjoy the civility and expertise in this thread of music lovers :-))))) my best to all
