88 db 4 ohm impedance... will need tube amps that have multiple output taps and decent current capability if the system is in a large-ish room and/or listening to be at higher volumes
audio research, vtl, cj, bat monoblocks would be where i would head... suggestions from magico dealer would be helpful
magicos needs tubes to calm the sizzly treble for sure... hope you live in a cool climate or have excellent, quiet hvac... :)
