@Wilkic65 With all the research that you will do and reading the information, it will also come down to what look do you want to have. One of the aftermarket add ons for the C1 is the black faceplate but usually on eBay are around an additional 100 doll hairs. Actually you can find both pre amps in both colors. And like I said today at work, the remotes are hard to find and costly if you do find one.
The remote add ons for the C1 only control the volume whereas the CT7 has more functionality. Its a crap shoot man. I have both and I like both.
Sounds to me if you like
