AR preamp, dac, Phase linear 400 amp, Yamaha dvd (av side), opus 2/1, 2/2 speakers and decent cables wire world, AQ and Van den. I'm playing the Opus 2/1 at the moment as the 2/2 are up with Willie for repairs. The system as it stands is so bright I can't stand to turn it up! I haven't heard the 2/2 in stereo only through my yamaha av amp and it sounded great so good I blew the speakers! How do I tone down the treble.??
