jetter, your comments are misleading suggesting a problem with ARC.
One can have issues with any product, in the end it's how such gets handled and receiving a Brand New replacement is as good as one can get and why you deal with a dealer so they can deal with such. I would imagine there are allot of ARC pces sold - do you know how many comparing too % of ones which have issues. I do not read much if any issues - does yours differ because you make such comments suggesting so.
inna, do you not like ARC?, if not it's your own opinion and maybe best kept there as many others differ like myself. Have you ever had an issue with any pces you currently or past have owned and if so were they replaced with a Brand New pce - most likely not.
The Ref6 and 75SE is a amazing combo and this is coming from someone with allot of personal experience with different manufactures, one can read back dated posting of mine.
I agree OP can look at upgrading other components which will further enhance his listening pleasure. :) and yes many cables out there are the prices of components and then some - it's a never ending journey.
