A pair of M250 Signature Monos in silver. Rated at 250W/8 and 500W/4 but sound much more powerful than amps rated at 500W/8 or even 1000W/8 amps. These will drive any speakers and YES!!! Including that famous (infamous) Amp Killer 1 ohm Apogee Scintillas. Of course muscle alone doesn't mean much if they do not sound good. These amps will drive ALL of Apogees and Maggies at Ear_Splitting level all day along while still maintain their composure and still stay cool as cucumbers :-). Not only they sound great on planar but they also sound great on other speakers such as Avalon Acoustic, Thiel, Dunlavy, Montana PNB speakers and many other highly regarded speakers. I understand there are Audiophiles who are being very dismissive regarding Icepower which I can understand but please remember, these are definitely NOT Run-Of-The-Mill Icepower amps. Icepower can still truly shine with a PROPERLY ANALOG POWER SUPPLY DESIGN and can still truly compete head-to-head with the best out there. In fact, if you have the Ncore amps which many rave about and are local to the Houston Area, I would love to do a comparison with the H2O either in my system or I can bring the H2O over to test drive in your system. Of course, this is not to see who is better but rather to learn the difference between amps and to find out how bad the H2O sounds :-) comparatively. Please let me know if you have Ncore amps and are local to the Houston Texas area. Thank you.
