Best Amp with Magnepan 3.6's


Greetings - I currently own a pair of Magnepan 3.6's and am looking for any suggestions on an amp that would help me get the volume/sound I am missing.
My current systems is as follows:
Magnepan 3.6's
Rotel 1057 preamp
Rotel 1080 (200x2) amp
NAD 525BEE CD player
JL audio F110 sub
Transparent interconnects, and cables
As you can imagine I am not getting near the volume I would expect out of these 3.6's because of the limited power of my Rotel amp. I have researched different amplifiers and have it narrowed down to 2 (although I'm still open to suggestions). I've been looking into a Bryston 4B SST or a McIntosh MC402.
I would greatly appreciate any input or suggestions you may have. Thanks in advance.

Bryston is great, and the Innersounds are also a good pick. Of all of these listed here in the thread, I have to 2nd the Pass amps and to say that as far as I can tell they are in a whole other league compared to most of what is mentioned here.

Innersound will have many more watts/$, but not quite the same sound in the mid and high frequencies. Bryston and Innersound are probably right on the inflection point on the curve of value/$ - the perfect place if you don't want to spend megabucks but want very serious gear.

That said, you can always pick up a used Pass Amp here or at RenoHiFi. However - be very careful. For Maggies, you only want to look at the .5 series (the most recent incarnation). So, for example 150.5, not 150. Or XA60.5, not XA60. (If you have 8-ohm speakers then it doesn't matter.) I would think that a used 150.5 might treat you really well and would be on the lower end for the Pass gear.

Some people say with maggies slightly lower quality and higher watts results in a more pleasing experience in the end. I have to say, I recently hooked up a kilowatt amp for 2 months (of much much lower quality overall than what I run normally) and it did bring out a different feeling than what I usually run and has me trying to figure out how to upgrade to higher watts.

In that vein, huge Kudos to Spectron as mentioned above. And - I haven't heard this but do wonder about it - as an interim value/$ play it would be interesting to do the highest wattage NuForce, Rowland, or even the super-high-wattage Rotel. I think that would be the 1572? 500 watts/channel at 4 ohms? And not very expensive compared to Pass or Spectron or even NuForce.

The drawback on some of the Class D stuff is the upper-mid and high range. So, if you got the 1572 for now, then in 3 years (or 3 months :)?) get something like a Pass Labs XA30.5 (Class A amp - extremely rare these days), and actively bi-amp, with the 500W on the bottom end, and the XA30.5 on the top end. That would be absolutely awesome! And a good value for what you are getting. I looked at the Rotel distortion curve vs freq several months ago, and the problems start well above the 200 - 250 crossover point that you would use on the 3.6s. The curve is totally flat below 250 Hz, can't remember, but I think it was 450 or 550 where it started moving up.
That said, here is a guy with Bryston hooked up to > 100k speakers.

The one thing I do agree with, is that people should focus more on speakers than the rest of the system. Many amps are extremely similar, same with CD players, but speakers are very, very different. I've found after many years of doing this that speakers and actually the pre-amp are the 2 critical pieces. I know there is a big 'source-as-important' camp out there as well, but for me many, many, many CD players and many, many, many DA converters sound extremely similar.
I am driving my 3.6Rs with Classé CA-M600 monoblocks at 1200 watt/4ohms fast, smooth, quiet, airy and
wonderful!
Just hooked up my new Wyred mAmps to my 3.6s.
Great bass out of the box with a deep soundstage. Can't wait for them to settle in after a couple of hundred hours. The sound is already very smooth and articulate and should only get better. Pretty incredible for $1800 a pair!

I have 3.6Rs and using Emotiva UMC200 pre/proc and an Outlaw Audio 7100 in a 14 by 14 foot room. So I don't need to turn the volume up to massive levels. The amp will do 100 watts per channel into 8 ohms and 165 watts per channel into 4 ohms. I have been thinking of getting a separate two channel amp for the 3.6Rs. I have read that it takes lots of current to get the best soundstage with instrument placement and depth. I am getting wide soundstage and good sound, but the depth is somewhat muddied enough to not get instrument placement. I am looking for a two channel amp that will give me more of the potential of the 3.6Rs, but be able to be purchased for less that $750 used.  Is there any amp that will be worth upgrading to for that kind of money or do I need a new pre/proc as well?
