Loudandclear. On the contrary...there is no such thing as too much power regardless of the speakers sensitivety. To begin with.... I am sure muralmans recommendation of the h20 was not even power related. While I have never heard the h20 amp, given the fact that Mondies speaker's impedence load can dip down anywhere near 2 ohms,I would think Muralmans recommendation is a certainly sound one[pun intended]! Hell...a 2ohm impedence load is getting dangerously close to a dead short for crissakes. Seems like Mondie would like to marry his speakers to a tube amp. Unfortunately... there are very few push/pull tube amps that can remain stable driving a 2 ohm load [let alone a set amp] without oscillating itself into china syndrome. Mondie... The only set amp that I am aware of that may be able to handle your speaker is the KR amplifiers. There are a few push/pull ones as well. Just be sure they have no less than 4 ohm impedence taps off the transformers and preferrably a 2 ohm tap. The original quicksilver 60 watt monos,the ones that employed the 8417 output tube[not the kt88] were champs at driving loads below 4 ohms. They were very musical even in stock form; and with a little updating with modern caps and resistors they should be a real treat. The older vac pa90 mono's are another great amplifier that would easily be up to the task. These el34 based amps can be used in pure triode or ultralinear at the flick of a switch. They also have a 2 ohm tap from the transformer and massive power supplies that are fully regulated. I am sure there are a few others out there as well. Best of luck in your search and have a very Merry Christmas!
