I personally don't think of electrostatic type speakers when I think of rock and roll. I'm not sure how much the Summits are, but if they fall in or around $9k, I would give Zuaudio's (a brand spanking new pairA of) Definition 1.5s a shot. They have an unbelievable moneyback guarantee, which you cannot beat with a stick: 60 days!! 101 db sensitivity. Jazz is my thing/female vocal/male and I can do reggae and good old fashion rock like in my Woodstock days. Speakers play with phenominal resolution at the lowest volumes and will drop your pictures on the floor at ear bleed level with only 100 watts. Would you believe they can handle 500 watts! There are oodles in the archives on the Definitions.
What speaker to buy to start over.
I am selling my entire system and starting over. I am considering Martin Logan Summit speakers. Any other suggestions in that price range. I listen to mostly accoustic and female vocal but do listen to rock,jazz and classical. I am going to build around the speakers.
