.. well i dont know if it matters because in a way these are different hiquality electronics, but i have been running 4 synths (two full keyboard and one antique), a drum machine, 100w amp, 60w fender tube amp, 14ch mix board, echoplex and other efx all on a 500w 240v to 120v step down since moving to europe in 1998 (with two 6 plug power strips), and the fuse has never blown in it... and i use i now use a 96khz 1000usd professional sound card for recording and have no problem with "noise" from the system on the recordings...nor in the speakers...
but like i said hifi might be different than musical instruments and digital recording...
