Thank you for your comments. I have bought the RF-62 during the weekend with the Denon 1611; I wasn't quite happy at first with the way it sounded, but after a few hours spent on positioning and configuring the Denon settings....YES, they are great ! And of course, what matters most is...YOU HEAR WHAT YOU PLAY If you play good quality you get the same...
Also, very deep bass on some special bass test melodies...(at some point it got scary, all the china, cabinets and walls were trembling
So, thank you again.
Cheers!
Andrew.
