I would look into the Placette interconnects. Very very transparent cables. We listened to a very long run of Placette cables (not quite 25 ft) and compared them to a 1.5 meter pair, and they were almost indistinguishable. Also, they are very reasonably priced.
Long RCA ICs - which ones fit this bill?
I plan to hook up a Pass X1 to a FetValve 550. As van Alstine amps do not have XLR ins I have to use single ended ICs. The kicker is that they need to be about 25 feet long. I spoke to both Frank, and Kent over at Pass. I am advised to use a straight coaxial design, fully braided shield, with as low a capacitance per foot as possible (<< 20 pf/ft if possible). The other kicker is that I don't want to spend an ungodly sum on these cables. What can I get in the cheap category that will fit the bill (not to exceed $1000)?
