SPEAKERS
Quote from departed Fi Magazine Jan-Feb 1997 Vol.2 #1:
"...I played a spectacular performance of Shumann's Andante and Variations by Martha Argerich and friends, EMI 5 55484; about two minutes into the piece, a solo French horn call is mimicked by the ensemble of two pianos, viola & cello; on this system with different, more expensive speakers, I thought that passage was played by two horns−quite a feat since only one horn was present; when I replayed the piece through the RS's, it became obvious that I was hearing the other instruments imitating the horn call." AllegroSolution: If your speakers are not able to differentiate piano and strings from horns, it's time to upgrade!
