Music to my ear.Was leaning heavily towards the 600i for my 3's and was only swayed by a silver Oppo HA-1 becoming available after waiting the better part of the year to find a good one. The Bang/Buck aspect of the 600i might be one of the best out there. Where did you get yours from?
Maybe I'll get the full Questyle Block or pair the CAS192D+CMA800P with a headamp GSX-2 in a few years but for now I need transportability as I travel often with my rig.
