I'm running Stratos mono extreme SE's with the newest form of Maggie 3.6Rs (X-overs are much larger).  The Stratos mono's are on cruise control and the sound is scary accruate.  I also am using a REL Stadium III, Audio Research SL-17 preamp, an ARC PH-5 phono and a very heavily modified Rega 25.  A quality tube front end is almost a must.  I expect this configuration to last me the next 10 to 15 years as the sound is that good and i've had the Mono extreme SE's 5 years now.
