Opinions on preamps

What makes you think the weak leak is the SFL-2? Have you tried different tubes, and you're obviously into LPs, why not try a tube phono stage.

You've also got a 4 ohm loudspeaker, no 65 watt tube amp is going to put out enough current into that load. Have you tried bigger amp.

I would suggest that you also consider the First Sound line up of preamps. I have a Paramount and have been extremely happy with it.

I would suggest the Opal. I have found this preamp to be a very quiet, excellent performer.It's build quality is topnotch and it's soundstage is very robust and lifelike. Although it's a tube preamp, it is not overly rich or warm sounding.I use it with SS mono-blocks, but it would be just at home with your VAC.Based on your comments about isolation and a dedicated room, I think you would be very pleased with the Opal's presentation, finesse,frequency response, clarity,top to bottom extension and it's ability to produce low frequency tones with definition & body.(You should hear an acoustic bass in a jazz trio!!)

What are you looking to accomplish with the change out? That would be a good thing to know.

I'm currently using an Audio Valve Eklipse. Audio Valve is a German company and doesn't do much promotion here in the States (imported by Victor Goldstein's Fanfare), but this preamp is fantastic -- some serious audiophiles (reviewers and manufacturers) are huge fans and owners. The transparency and dynamics are stupendous -- in fact, I sat in my listening room this evening with a leading speaker designer and we were wowed. There is a matching issue -- some amps don't work well with the Eklipse, with the result that you hear upper midrange glare -- but if you get a good match, you'll be amazed. Good luck.
