Go for the 1602, Denon do have quite a few good amps for sale at the moment. I would say Richer Sounds are not gonna make any commision on the Denon amp as they would Technics. Or.. they dont want you to leave the shop without nothing..
Richer Sounds know that people dont wanna go home empty handed,so people go away with different products and Richer Staff make a packet of money. Dont get me wrong,, Richer Sounds are very good for buying products cheaper, but they do try and sell you something different, time and time again
