Thank you for your comments. Sorry Plato, I don't know where the 1200 watts came from, but may have been supplied by the site. Bob_bundus is right in correcting the watttage. Actually I only have the Wavelength Duettos (8 wattts/channel) right now and may never get to the Wavelength Tritons. Thank you for the advice on preamp idle noise; it is something I'll have to look into carefully.
