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

Also these are being used in a phono stage and not a main pre so maybe there is a difference.

The M-Steelhead eh. Now there’s a Manley mans piece of gear there my friend.. Tell me how much you like it.

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.
