I just recently purchased this cable used, I can say right off the bat I can hear the finer nuances that were slightly veiled before. Initially they sounded crisp, then just a few minutes later they became slightly dull and muted in the midrange. I have read about the roller coaster ride and that's definitely true. I let the CD player go for about 25 hours and what I have found is that the vocals sound almost within a very narrow range of frequency and about 2-3 feet behind the speaker. Almost like I have a 2" diameter full-range speaker as a center channel (in a 2ch setup) producing the vocals, very little dynamics and midrange. My question is basically what's the time frame for a used cable as opposed to new for a break in period? I can tell that the details are more evident but the midrange and overall dynamics are all over the place. Soundstage is wider and very detailed. Overall I'm happy but just sharing my results. I have the MA3 at both the CD to pre and pre to amp, both cables are used.
