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!
