I am currently evaluating my first pair of Morrow ICs (MA3 with Eichmann copper RCAs), connecting my DAC and preamp. The difference between this cable and my previous cable, Monster Reference, is simply jaw-dropping. The cable is not yet fully broken in, but it is showing me all the things the Monster was doing wrong. I hate to even type this (let the flaming begin!), but this single IC swap transformed my system for the better in almost every respect. After discounts and sales, a 2 meter run of the MA3 with the Eichmann RCAs ran me just under $300 shipped, including an upcharge for 10 days of burn-in. Morrow has a generous trade-up program and a 60 day return option.
I will just say this about cable skeptics. I hear what I hear. As far as I can guess, cable may not be able to improve a system, but sure can mess up a system (the Monster cable turned out to be the culprit for a few issues I assumed were in either the speakers or the electronics). Finding cables that do the least harm to the signal without costing a fortune seems to be a reasonable goal.
