Thanks all for the response.
I am quite surprised actually to find that most responses are having good experience with sounds like some had good experience with relatively 'small' amps (8 to 30 watts).
For gliderguider, tpsonic, and thorman, have you had the chance to listen a ss amp driving your speakers? If yes, do you think the tube amp still drives it better?
I am also very curious on comments from Bigkidz. Could you explain more on why matrix series' crossover need higher current to come alive?
The tube amp, I have in mind, is BAT vk 60. Am wondering whether this is enough to make my speaker sings. My music genre varies from jazz vocal to percusion to pop.
My current systems are: electrocompaniet emc1 cdp, audio research LS22 pre, audio research d400mk2 power. What I like is it has the dynamics/fast/speed/slam for music type like fourplay (max-o-man)or michael jackson (black/white). I feel the smoothness of midrange/vocal on jennifer wearnes/holy cole trio is not quite there yet. Not sure whether I am asking too much out of my systems.....or maybe I should consider bi-amping...?
