17 feet IC to long with Coincident pre and Franks?

It would probably be best to ask Mr. Blume of Coincident. But my guess, given that the output of the CLS is transformer coupled and has a specified output impedance of 500 ohms, is that if you use interconnects having low capacitance (less than say 25 pf per foot) you'll be ok.

Also, the description of the CLS indicates that it provides an AC ground lift switch to minimize the possibility of ground loop issues. In general, ground loop issues (low frequency hum and/or high frequency buzz) tend to be especially likely to occur when long unbalanced interconnects are used, if neither of the connected components has that provision.

Yes, call Israel and he'll give you an informed and straight forward answer.
My gut feeling is you'll be okay. Mikha65 what are your speakers? With the
right speakers I believe that you'll appreciate the Franks as much as you do
your CSL.They re cut from the same cloth. Best of Luck.

ALL I was gonna say was ping Almarg or Israel Blume.
What's happening with Antique Sound Labs these days anyway, all I ever here about are the Frankenstein ?
