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?

Decooney you have to ask Mglik about the quad of psvane tubes I was just quoting his post about vintage tube service.

@invalid  ok, did not see it as a quote. Will try again, Thx.  

@mglik same question, above. And did the tube reseller offer you a return, refund?

Ralph @atmasphere was my primary reasoning to try the 6SN7. No one is kinder, smarter and with incredible patience.  However, he hasn't been able to talk me into his class D AMPS yet.......

 

A week or two ago someone posted about removing the PreAmp from your system and go direct from the DAC . I tried for a week . It was clean, clear and had Dynamics  but........lacked  engagement . I of course but the pre back in the system yesterday . 

Ralph's UV-1 preamp gave me my first taste of 6SN7's. That small simple circuit produced a huge soundstage, music with weight, and layering of textures. I've moved on to another 6SN preamp and an Atma-sphere S-30 which uses (6) 6SN7 input tubes.

 

Vintage tube service tests them in circuit, he has many different components to test them in.

@invalid , thanks for posting this. Andy has pics of all his testing gear on the website. Many years of purchases and I've never had a microphonic tube. Also the lowest noise of all my tube purchases.
