The Perfectwave PowerPlants (including P3) are on sale over at PS Audio. I guess the Stellar PP3 is part of the Perfectwave line?
The P12 looks very compelling (especially at sale price). Admittedly, never thought much about power in the midst of headphones, amps/dacs, etc., but am reaching the point investing in something like the P12 would be worth it. I can attest to the day/night phenomena, if anything, which the P12 (and other like products) are supposed to help out with. Gotta go easy on the wallet, got drawn in to the SACD transport
