Well, a lot of highs really, but the thing that makes it most special for me is the midrange of my Stax F-81 electrostatics. With the POSSIBLE exception of Roger Sanders’ electrostats I have never heard a more realistic rendering of midrange. Soundstaging is also fantastic, but on a smaller scale than many audiophile systems. What would I change? I wish their bass extension were on the same level as the rest of their range. Quality is very good down to the lower mid bass. After that my two REL subs take over with fairly good success. A bit frustrating, but no way would I give up that midrange.
What Makes your System Special?
Could be anything but interested in what makes it special for you. Is there something you would want to change?
