I have had a MS600 as well and was able to compare with a 218, both unmodified. I though the 218 was slightly better. Somehow I never was blown away by the MS600, certainly not given its size. I have used the balanced analogue outputs as well on a set of active ATC SCM20SL which wasn't too special. So I kept my 218 and sold the MS600. I think the DSP7200 can use a better front end and to my ears the 218 with a LPSU made a big difference. The soundstage became more realistic and refined. A difference that can be easily picked up with a blindtest in my system. I have to note that I can't go back to the original PSU, but I used the MS200 SMPS for testing.
I would recommend it.
