Tube Recommendations Please

I use an Audio Research PH5 phono preamp.  It is the only tube gear in my system, and I am far from an expert in tube electronics.  I've had the preamp for at least a decade, and I am feeling it's probably getting to be time to replace its four 6922 tubes.  The problem is that I don't know how to go about selecting from among the various brands that I see online, including Amperex, Telefunken, Electro-Harmonix, etc.  Can anyone suggest tubes that will be quiet, reliable, and provide both midrange warmth and a tight, extended presentation in the high and low ends?  Yes, I want it all ...

FYI, the rest of my system is VPI 'table, Lyra Delos cartridge, Ayre Acoustics amplification, Vandersteen 5A speakers, with all cabling from Audioquest. 

Thanks for any advice, and happy listening!  


there are 50 million threads available on quality tubes for a given tube spec.  search and read them.  e.g. "best 12AX7".  

personally I use NOS for small signal tubes, they sound the best.  

make a selection, buy from a reputable dealer and try them.  if you are serious about it trying different ones is the best way to find what you like.  

     Well: I thought how Brent noise-tested tubes was on that page.

     Here’s how he does it, on YouTube:

     Note the socket, for nine-pin miniatures, to the left of the octal.

dawgfish, what you described is the Amperex from the late 50s and early 60s, either Holland or US.
