There is an upgrade from the MS600, but that�s called the 818!
Though I�ve not heard one myself yet (dare I get one on home demo!), the 818 is said to be now be the highest performing Sooloos �source�.

I think your perception is correct. Having listened to C15 to 818 to M6's at Meridan Oxford, I was impressed. IMO the excellent performance from the M6's was derived from the 818. Others comment that 5200's are superior to M6's. Can't argue with this POV but would be very happy with a comparative demonstration. How much better are 5200's fed from 818? Hopefully by an audio mile.
Please take a home demo of 818 and report soundings.
