Here's the other half:
I auditioned my Summits with a BAT VK51SE (preamp,) an ARC VT 100 III (amp,) an SME model 10 tt with a Graham arm, an Esoteric DV 50s (for digital sources.) All amplification equipment is tubed. I have owned ML speakers since 1990. I've owned 3 pairs (not including HT components) in total. Prior to the Summits, I had Sequel IIs and Ascent is. I was expecting an improvement when my new speakers arrived, but I was not prepared for the improvement that I got. Music now has a weight, a feeling that I never experienced with MLs before. The woofers are indistinguishable (by me) from the panels. This was always noticeable before. Spatial depth and stage dimensions are more easily heard with the new speakers. No part of the musical frequency spectrum seems to be emphasized at the expense of another. There is no treble glare; there is no bass boom. I'm sure, if you spent $50,000 on speakers, you could do better. For my purposes and budget, these are the ultimate. I could go on, but I'll spare you.
