hello, i have an 11 years old Onkyo tx-8411 (100w) stereo receiver which i would like to replace. it is paired with B&W 603s1 speakers which i won't be replacing for the next several years (i would like to...), and a cheap LG DVD player, i use it quit a lot for: music, radio and watching movies. my budget is tight and from reading reviews and some forums I've narrowed the list to: a. Cambridge audio 540A2 b. rotel ra-04 i've listened to both amps (in a show room) but not with my speakers... i'd like to get your opinion on these amps paired with my speakers. does anyone think that buying the Azur 540R (home theater) is a good option, since it costs 50 pounds less? anothr option is a used audiolab 8000A thanks for your help
