Does anyone have experience with a MX-117 and C-28 and have opinion as to how they compare? I currently have a very nice C-28 (serviced by Audio Classics several years ago) and use with my MC-2105 amp. I like the idea of having tuner/preamp in 1 unit and am thinking of purchasing a MX-117 to replace my C-28. I could use the MX-117 with my MC-2105 amp or my MC-7300 amp. I'd appreciate any thoughts on how they compare.
