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.

Bkonig- I have a custom built passive preamp and I also own
a SFL-2. If you're hearing "grung", then your SFL-2 needs new tubes, adjustment or it's defective.

I'm sure your VAC is a 65 watt powerhouse(for $14K it should rock your world), but like it or not it can't generate much current into a 4 ohm load. If your speakers are rated at 4 ohms, you can bet they dip below that level.

But hey, if it's floats your boat, you should unload the SFL-2/Klyne and buy the VAC Signature Preamp w/phono and complete the deal. Mixing active components from different manufacturers is always tricky.

Stick with what works best for you.

Good luck with your quest.

Dennis_the_mence- You're a hoot.

"I can't ever get the volume dial on my preamp past 11 o'clock."

"The VAC, according the Kevin Hayes, is sensitive, and needs a preamp that has LOW gain, ideally around 10dB."

Now you know why you can get the volume control past 11 o'clock.

Volume setting have nothing to do with power output capability, as Mr. Hayes has shown you.

Aloha.

Dennis_the_menace- I love you guys with your mega buck amps.

To answer your questions, I'd never spend $14K on any amp. That said, I have no reason to speak with Mr.Hayes, unless he'd like to play some golf on Maui.

I'm sure the VAC is a great sounding amp. Since there's no hiend dealer here in Hawaii, I'll never get a chance to hear one.

I do know that no 65 watt tube amp on this planet can generate much current into low impedance loads. If it drives
your speakers great, but please don't confuse volume settings with power output.

Aloha.
