Amp question for Maggies

thanks for the info, that is way more depth than I can comprehend, I think my ARC does a good job of getting fairly high spl(I have not measured) but I believe the ARC may run a little shy on power if pushed hard, I am worried about switching at realistic listening levels the ARC sounds very good, I am more worried about what type of change in sound would incur if any if I switched. Thanks for the indepth info.

Have you looked at the new Carver mono blocks? The first generation Black Beauty 305's uses KT-120's (approx 350 watts into the 4 ohm Maggies) and there is also the Cherry 180's which is approx 225 watts into 4 ohms.

I have the Magnepan 20.7's and have tried a lot of different power amps and so far nothing is close to the Black Beauty's performance. There is no question in my mind that the Black Beauty's seriously out perform several 1,000 watt solid state mono blocks that I have tried. With Maggies it is just not all about "watts".

The Black Beauty's do not break a sweat driving my 20.7's no matter how loudly I play music! Check Audiogon, AudioMart, and WattSpot for a nice used pair of the Black Beauty's or even the Cherry 180's; they will drive your Maggies like you have never heard!

Maggies are well-known to be power hogs. Additionally, IIRC, they also dip down below 3 ohms at some frequencies. For these reasons, they work best with amps that big pwoer and good reserves of power. You could easily make use of 500+ WPC.

Look into getting something like the D-Sonic M2 Series digital amps (http://www.d-sonic.net/) or perhaps one of Emotiva's XPR line of Reference amps like the XPR-2 (https://emotiva.com/products/amplifiers/xpr-2). Both of these companies provide a 30 day in-home trial thus allowing you to really hear how they sound before you commit to them long-term...

Spectron Musician III works for me on my Maggie 3.7s.

The Sanders Magteck was designed around the Maggie's you might want to audition they have a 30 day return.
