+1 for Brent Jesse.
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!

Well: I thought how Brent noise-tested tubes was on that page. Here’s how he does it, on YouTube: https://www.youtube.com/watch?v=205__gxWJc8&t=32s Note the socket, for nine-pin miniatures, to the left of the octal. |
Pulling this back out but have to share... went from stock Sovtek 12ax7s in my Calypso to NOS Mullards from Upscale. I thought they were terrific in this Linestage. Of course, never satisfied I brought in 2 vintage matched Telefunkens pushed by the hype... they are/were magnificent. Hype realized however, I just came across (8) NOS Tungsrams, yep 8! I can emphatically say this the finest my Calypso/system has ever sounded. The Tungsrams are balance with a deep snappy bottom and just the right amount of sizzle. The midrange is milky smooth and the soundstage is deeper and wider than I have ever experienced. I know these are pretty rare and honestly, where these came from, there's no doubt the origin owner (hoarder) of these incredible tubes knew exactly how magical they perform. I'm not going to keep them all but I am keeping (4) and will sell off the other (4). If anyone's interested LMK. |
