You might also want to try using a good subwoofer crossed over below 100HZ electronically 18 or 24 db/octave. This will eliminate some of the glare/strain on the midrange and increase the effortless sound. Tune in the woofer with a solo piano disk.
Need help from Quad ESL 63 owners.
I have a pair of Quad ESL 63 speakers, ARC Classic 60 power amp, ARC SP8 preamp, Oracle Premier TT, Ruby 2 cartridge and EAR 834 phono stage. I am experimenting different cables, IC and power cords for my system. I listen to mostly classical music, especially strings and piano music. I need some inputs. Thanks.
