You may be doing yourself and the M60 posse a favor by listning to your M22s on your new system, rather than tubes. If instead you were listening to M3s on a tube set you may well have fallen into the seductive allure of that well documented "match made in heaven." That slippery slope may have lead you into the obvious M3 upgrade, the truly near stand alone M50. You might then be coming over to the growing M50 posse instead!
