Welcome to the forum, GeneK. I'm not sure if you've noticed, but there's been a running discussion in the RR2150 section of the forum about the unit's knob "quirks." Most of us owners don't mind them, but my guess is that they won't be so easy to explain to those AV folks who perceive "knoblessness" as modern or futuristic. Just a thought…
