Has anyone upgraded their preamp with V-caps?

I am interested in hearing about anyone's experience with upgrading their preamps with V-caps (in the output circuit). They are very expensive, i.e. 600.00 for two 2.0uF. I have heard that they are amazing caps and make a huge audio improvement, particularly in the bass and midrange.

Dgarretson,
Is that .1uf cap for the output coupling position?

This is a good thread; my suggestion would be to pay special attention to upgraded power supply anytime you are thinking improvement.

If you opt for a V-cap, do explore quality power supply.

It is .1uf in the LS and .47uf in the PS of my late model Atma MP-1 MkII. I believe Atma used other values in various vintages of this preamp. It sound f***ing great with the V-Caps.

Sherod, the output of the MP-1 is direct-coupled; the pair of 0.1uf caps (the unit is also differential) are between the voltage amplifier and the vacuum-tube output buffer.

Thank you Mr. Atmasphere. I have asked this next question in other threads and haven't received any answers yet: How does the Sonicap Platinum cap compare in sound to the V-Cap TFTF. I realize that the V-cap is almost twice the price, but is it twice as good? I am debating between the two for the outputs in my preamp which require 1uf or so. I have tried the V-cap OIMP and although it sounds very nice, it has a little too much warmth and roundness to the sound for my tastes in the preamp outputs.
