Magnepan 3.7 speakers + Audio Research Ref 75 amp


Magnepan speakers have an average impedance of ~4 ohms and generally need LOTS of power. Tube amps rated at under 100 watts need not apply. So I'm told. I've also heard that Magnepan and ARC have a synergy that may be hard to beat, though I can not say I have ever listened to this combo.

So, my question is, would a 75 amp from ARC (with a power supply storage of 520 joules) be sufficient for the 3.7 Maggies in an 18' by 30' room? Has anyone heard or heard of this combo before?

Thanks in advance!

The combo should sound and work very well, but at low to medium volume levels. The 3.7's are not very efficient, but the Ref 75 should have good control over them up to its rated output. It would mostly depend on your listening habits.
500 SS watts at 4ohms would do better.
Schubert is right on. 500wpc into 4 ohms is ideal Low power tubes are just not enough. Try a Carver 300wpc amp or big Manley. Then the 3.7 will have some dynamics.
Jallen, don't mean to butt in here but have you heard the manley 500 or 250 with the 3.7's? I have the 3.7's driven by Cary 500.1 MBs (1000 WPC into 4) but have wondered how the Manley's would do.
I have a dual mono version of the Odyssey Stratos (2 mono blocks in one enclosre) powering my 3.7's. I couldn't be happier.

I used to have a pair of Accustat IVs that I drove with an ARC Classic 60. Nice within its power range for sure. Then one night a friend brought over a pair of Van Alstine 200 watt amps with Van Alstine's bridging devise. We hooked everything up and with the bridged amps we were getting around 800 WPC. Oh MY GAWD! Nirvana! If I owned a pair of the new Maggies, I'd go with that same Van Alstine setup.
