If your upgrade itch is FOMO over SQ, try some cortisone cream. The units will sound the same, just like your C50. McIntosh Labs engineering doesn’t suffer from audiophilia nervosa. When they’re done with a design they’re done. The next project looms.
McIntosh C52 to C53 Upgrade
I had a McIntosh C50 pre-amp/DAC that I replaced with a C52. Now thinking about upgrading to a C53. For those of you that have gone down this path, is this a worthwhile/noticeable upgrade? Any noticeable change in SQ? I can't say in all honesty it was noticeable to me going from a C50 to the C52.
