Bi-focal xl's are sounding great between my cj mv-55 and Alon II's. I too had seen reviews saying they were a bright sounding cable. I believe this coloration may be system dependent and/or due to lack of break in. Up to 150 hours I thought cables sounded unaturally bright giving digital playback an edginess that was fatiguing. At aprox. 150 hours this edginess disappeared but there was still a bit of brightness. At aprox. 275 hours the cables began to bloom, sounding richer fuller, more dynamic, increased soundstage depth and height as well. I now have aprox. 300 hours on cable and expecting further improvements. It seems that reviews claiming 500-600 hours of break-in are likely correct.
