Hi guys first post so please be kind,at the mo i have a cambridge audio 340r amp powering a set of monitor audio radius speakers(bipolar rears) I only have about £200 to play with which i no is not a lot may be a bit more when i sell my 340.Any way i have been looking on the web,in local stores ect and they are saying i have to spend between£300-£500 to get an amp that will sound better than mine(something that i can here a difference) I have been looking at a denon 3802 i know that it is an old amp now but would it be a good upgrade for me?Also a lot of shops do not seem to like sony amps but on here the str-dh810 got five stars.I dont have a blueray player at the mo so will the denon sound better /as good as the new formats and would it be worth getting a new amp ie the sony? please help this is rearly doing my head in so good second hand amp or not so good new one thanks for your help
