Hello 3.5max6spd, I purchased the profi vanadium phase plug comp and it came with the cal26 titan, how is that compare to the cal26 silk and the cal27? I'm really thinking about getting the cal27 from premiere audio and try it out, the majority here likes the silk better anyway. Since you've heard all the rainbow tweeters, your opinion is golden. BTW, would it be ok if I use the x-over that came with the phase plug for the cal27? What would your preference be on the x-over settings for the cal 27? Thanks.
