What made you change to a 6SN7 preamp?
If you made an intentional shift toward a 6SN7-based tube preamp, what sonic characteristics motivated your move?
I have been doing some comparisons and think I have some reasons I like the 6SN7 better, but there are so many factors which could be at play, that I'm not sure what is responsible.
Rather than list my details for others to analyze, I'd rather hear your answer to the basic question.
Tell me about your path toward a 6SN7 preamp?
What did you change from and why?
Even if, overall, the change was worth it, did you lose anything in the transition? What?
@atmasphere Ralph, I think you were reinforcing the point I was trying to make that it's not all about the tube? Interesting to hear the 6DJ8/6922 was intended for use in TVs. @hilde45 I don't have any experience with the Quicksilver preamp you have listed in your virtual system, but I think you'd find the Herron preamp a night and day difference. |
@lowrider57 Thank you for relaying the story about that upgrade. It bears on my question directly. Very helpful. @moofoo Your example, too, bears on the question. And as others have said, there's no substitute metric for actually hearing it. Expense, tube, design are all relevant to the question, though. @big_greg Thanks for your comment about the Herron. I need to sell something before buying anything else, but I'll keep my eye on that Herron. My Quicksilver got upgraded with Mundorf and Vcap caps and sounds pretty good. A night and day difference would really be the reason to change. |
That is true. But if you work with tubes over time, you get a feel for what they do. More to the point though that in order to really compare what the tubes do, you have to make sure all the other variables (circuit topology, part quality, grounding technique, power supply design and so on) are put to bed. We see this going on in the SET world all the time- SET fans say they've compared SET to Push-pull, but when you dig into it you find out that the variables I mentioned above were uncontrolled in the comparison. This makes comparisons invalid; all you can conclude at that point is you might prefer one over the other without knowing why that is if you're being truthful with yourself. |
Unrelated to the thread topic but important to those looking to optimize their purchases regarding NOS tubes, Andy @ Vintage Tube Services is the guy. Give him a call, you'll be rest assured he knows his tubes and upon ordering you'll also find yourself grinning from ear to ear. He's a passionate and perfectionist audiophile. |
