im now a very very proud owner of the incredible 600i. befor the 600i. ive owned the mcintosh 252 power amp with mcintosh c2200 preamp. it was great stuff and enjoyed for many years with zero problems. but now it was time for change and i got back into beutiful audio market world. after a couple of months of looking around. the moon evolution 600i was the one. it clearly put the mac to shame. this isnt just any integrated amp. its a seperate amp beater. moon audio is for shure the gear to own. and its definetly the best for the money.
