    I know, but I gotta to show off someone's hard work...

    That's really nice.  What changes did you notice with the new caps?  I'm going to mod my WA22 sometime, although I haven't started researching different capacitors yet.

    I can't answer this, maybe Danny can charm in.  I brought his amp that is modded already...

    That's the way to go. The Black Gates should give a more vivid sound, and a quieter background. That is my experience with other gear.
    I would like to know if the V-caps improve the lower range. My WA22 is stock except for tubes. The upper range is better than the lower range.
    Any suggestions for modifying ?

    I have been agonizing over the same issue. The WA2 comes with a standard preamp out, but how good is the custom balanced preamp out that Jack adds to the WA22? That puts the WA22 close to $2400, at which point I might as well look seriously at an awesome piece of equipment from Ray Samuels. I'm happy I found this thread, but I don't really see an answer to this basic question. How good is the custom WA22 as a balanced preamp?

    The custom balanced preamp out that Jack adds to the WA22 sounds marvelous, beautiful and dead quiet. My only complaint is the location of the pre/headamp switch, particularly if you don't have easy access to the back of the unit. And having to add/remove the SE load plug isn't exactly convenient either.
    So from an audio perspective it's absolutely perfect, but the conversion does have its ergonomic/functional shortcomings.

    Awesome. Good to know. I'm curious: What amp / speakers are you driving with the WA22? Source components?

    (phono amp)GCPH/Gungnir > WA22 > RA150(speaker amp) > WEE
    I also has Woo change the SE input to a second balanced input. The switch is almost as inconvenient as the preamp switch but not quite.
