DADS...
please refer to the following link...
[Link: audioreview.com]if you surf through the myriad of dedicated tuners and reviews, you're likely to find the tuner of your dreams, with discrete codes...
BTW...the Denon is not good except in HEAVILY populated areas...the PARASOUND is fantastic, and several yamahas are not bad!
U;timately though, you'll of course want to go with Magnum Dynalab...unless 3500-15,000 USD is out of range for a tuner?!
