Has anyone upgraded their preamp with V-caps?

Jppenn,

Thanks for the details. I was wondering about replacing all the caps or just upgrading those in the signal path.

I am aware of some possible downsides and will tread lightly.

I thought the OIMPs were the Top-of-the-Line?

Here is the v-cap web site. The TFTF's are the more expensive. http://www.v-cap.com/

Jppenn -> you are right. Using multiple V-Caps may have a cumulative effect on sound quality.

Atma -> I agree that you can DESIGN an excellent amp around V-Caps. Simple cap swapping is a different story.

I second Atmasphere's comments.

V-cap upgrades in my MP-3 pre and M-60 amps have improved the sound far more than any tube rolling (and I've tried many different tubes).

That said, even V-caps do not alter system sound nearly as much as a synergistic component (i.e.source/pre/amp/loudspeaker) change, but that's stating the obvious - I hope!
