PS Audio Multiwave

In my own system with Quad 63s (AC powered), it was a bigger jump than installing the original PP300. Quieter, more depth, and more 'harmonic integrity'- fuller sounding, but quicker on attacks and decays. Extremely happy with it! Your own mileage may vary......... Installation is a snap, almost literally. One board and a chip. It takes longer to read the comprehensive instructions than to do it! About 10-15 minutes total.

Tsouthworth and audiomark, I am interested in doing the upgrade as well. Please tell us how much the upgrade is. Thanks guys.

I agree, the installation was very easy, just follow the instructions and you should be done in aprox.15 minutes. The price of the upgrade is $250 if either you or P.S. Audio does the upgrade.

Does the new P300 come with the upgrade? Thanks Richard

I am considering the multiwave upgrade kit and have read a couple of posts at Audio Asylum that claims that the Multiwave upgrade causes the Power Plants to run hotter.I know about the possibility of an internal or external fan and do not care to resort to that as of now.Any feedback on this is appreciated.Turning the Power Plants upside down will make them run cooler as well as cause them to look ridiculous and totally unacceptable.To Richard : New Power Plants will come with the Multiwave for $250.extra.
