Hey, I've seen a lost of mostly good reviews of Denon mini systems (D-M31S mainly) - but I can't seem to find much info on the D-F101MB system. Does anyone have any first (or even second hand) experience with this system? Or maybe know of a link to a professional or user review? Or can someone deliver any somewhat well informed opinion of it? Also has anyone bought a denon "factory refurbished" product? 90 days seems like a kind of a crap warranty. Do they not trust their own repairs? Thanks in advance.
