The things I read on this forum are absolutely comical.
First of all, Jmrgrogan2, I guarantee you didn't look up the input impedance of his amp BEFORE I said anything. If you did, anyone knowledgeable about the 17LS would have still made the comment in case he decides to ever change his amp.
Secondly, if you find your ears bleeding with ARC and Nordost combinations, then I'm an super eager for a picture of this complete system setup and what source you were using.
Anybody who screws up an ARC + Nordost combination to where "your ears bleed" has no business giving advice on this forum...Sorry to be harsh, but the level of ridiculousness on this forum has to stop!
