Hello ricred1, I didn't want to imply that your speakers are inferior in some way- I have never heard them. But one example i can offer is the day i heard Wilson MAXX
speakers and then after those the Alexandria's at a local store. The upgrade was like
an entirely different way of experiencing the music. Both speakers cost
a huge amount of money, but I couldn't even consider buying the MAXX's after hearing their flagship model. In my own home i upgraded
from B&W-801s3 to Eggleston Andra's (and then to Andra-II's)- really no words can describe the improvement or the enjoyment i got from listening for hours on end. I gave up the Egg's for Von Schweikert speakers and gained much more midrange clarity.
So i took a different path from you, and since there are no Monitor Audio dealers around town the issue never came up. I am also a huge fan of Sonus Faber's (a friend has a pair of Extrema's which sound out of this world).
You could improve your source components and/or your cables as well, but looking for a "better" amplifier than Rowland is IMO is going to be difficult. Plus you have the Corus preamp as well, so as one dealer told me when i purchased a Rowland Consonance w/phono a number of years ago, "you're done"- i.e.- go improve some other piece of gear.
Even today, that is one hell of a great preamp.
