Changing Preamp tubes on a Cronus Magnum?


In an earlier thread, I mentioned getting my Cronus Magnum on Friday. The amp was well broken in when I got it and I have put at least 24 hours on it since receiving it Friday morning.

I want to ripen the midbass/lower midrange a bit and from what I understand, it's the center 12au7 tube that makes the most difference. What would be a quiet tube that will ripen the sound a bit? Thank you.

I have the Cifte in the pre-amp position on my RCM as well. Very nice tube, 3D soundstage is correct. The Cifte is flanked by two La Radio Technique Green Box 12au7's. I have 2 Mullard 12ax7's on the way to replace the new production Tung Sol's in there now. Anxious to hear them.

Soon I'll be getting a nice Mullard 12au7 to switch out with the Cifte to see which I like better.

Got everything from Kevin at Upscale, very happy with his selection and customer service.
