You didn’t mention how far away your Maggies are from the front wall. In my experience with Maggies, they MUST be a minimum of 4 feet out to get optimum front to back imaging. Anything less and the soundstage will suffer and no amp is going to make it much better. While a lot of people say 3 feet out will work, they don’t fully open up until they’re out 4 feet or more. If you are unable to bring them out that far, diffusion and not absorption behind the speakers will help with imaging. Try pulling them out to 4 feet (if they’re not already) and toe them in slightly, before spending money on an amplifier.
Budget amp that will give Magnepan 3.6Rs better depth of soundstage
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?
