Which tubes are better...

Wig,

I tried the RCA clear tops also, (in addition to ALOT of others). They are good, but not on the same level as the Mullards...in the Belles preamp anyway. You should really enjoy the CV4003's.

I believe my GE 12AU7A tube are on their last leg which I thought are rather new since the unit I bought was a demo with light use. I have been noticing static in the right channel but thought it was the running washing machine or dish washer. But after swopping to the Jan 5814A two days ago, the soundstage snapped into focus and there's much more detail and ambience. I can't wait to get the Mullards and GE BP 5814A triple micas. I know for a fact that my MIT S3's are a bottle neck in my system and hope to find something that is neutral.

I received both CV4003 Mullards and GE 5814A BP triple micas. The BP are very neutral and the sound is phenominal, open, detailed and dynamic. I'll try the Mullards in a few days to see which ones I'll decide to use.

Wig, you realize that when that pre-amp is plugged in the tubes will stay powered up, albeit at a lower voltage 24/7.
Now aren't you glad I gave you the tip on those Ge's.As for the CV4003 I will boldly state that IME they are awful.

Good luck

Reb1208,

Thanks for the recommendation! I'll let you know how the Mullards sound in my system.
