Thank you Rives. Tele's seem to be the thing!
Thinking about a tube roll to Brimar or Telefunken
I am presently happy with the performance of my Aesthetix Calypso and Rhea. But, I'm wondering if there is anything else out there (that I'm missing). Presently the pre is running the stock 12AX7WB and 6922 Sovtek. The phono pre is running 12ax7LP,12AX7WB, 12AX7WB, and 6922 Sovtek for the respective gain stages. My question is this. Does anyone have a little experience/advise on a tube roll to improve what I already have going for me. Understand what I'm not trying to do is attenuate a particular problem, these pre's have none IMHO. Just looking for an overall improvement, if there is such a thing. What about Telefunken smooth plates NOS or Brimar long plates CV4004? I have seen threads on Aesthetix Callisto and Io tube rolls but don’t know if the logic is transferable. Thanks for any and all help as always!

R f Sayles, Have you read "Joes tube Lore" for 12ax7 and 6922 tubes. http://www.audioasylum.com/scripts/d.pl?audio/faq/joes-tubes.html |
Jea48 Thanks and yes I have read the whole thing on several occasions. In the final analysis he seems to fly in the face of generally excepted favor of Telefunken being the Holy Grail. That’s interesting. Fact is there are plenty of other tubes out there to choose from. Don't believe Joe ever divulges his "rig" and that is a shame. It leaves us with no point of reference. No doubt there is a wealth of observation there. |
Joe S is a friend of mine, we have spent dozens of hours on the phone over the last few years and traded countless emails. Joe is a VERY intelligent person and a very careful listener. His reference speakers and amplifiers are the ones I sold him, Sound Lab M-1 and Wolcott Presence 220. He and I agree on some things and disagree on others . The rating of the Telefunken 12AX-7 is an obvious example. For what it's worth, most audiophiles and tube experts classify the Tele 12AX7 as the "reference" design for this type. Needless to say, I agree with the majority :^). As for the RCA 5692, I have tried many versions of it and agree it has merit. Some equipment, particularly the Aesthetix, simply DOES NOT work with the RCA, offering dismal results with it plugged into it's circuit. As with all things audio, the associated gear, personal taste, room acoustics, listening volume and many other factors enter into the equation. I advise you experiment with Tele's, confident that if you don't like them, there are a hundred people waiting to take them off your hands. Good luck with your tube rolling adventures. |
Albert, Thanks again for the added info. and tipping us off to your association with Joe S. Again I find your help invaluable in my pursuit of the music. Audiogon threads can sure be a lot of fun with banter flying every which way. In this particular case the wisdom of those that have already "been there" is saving the rest of us great expense and frustration. Thank you. |
