Can "Dark"Sounding Speakers Be "Brightened"UP???
Yes. There are many ways to arrive at a similar destination. Dark speakers can be lightened up by using brighter gear and/or cables, and vice versa. Many people do this without realizing it. They may say "that cable is too bright", not realizing that they are running bright speakers.
I ran Verity Audio Parsifal Encore's which are very dark sounding, they are the first speakers I ever heard where silver cables sounded good. I also found that more revealing electronics worked well with these speakers too. ARC and VAC worked better than Cary or CJ.
