Hi, I've been using an integrated sony DAV 500 system and (finally) have decided to upgrade so I can play DiVX and Xvid discs. I've seen good reviews for the Pioneer 575 but it's occurred to me that, while it has onboard 5.1 decoding, it won't have an amp like my current system. I'm planning to keep my speakers (they're not great but I live in a flat and my neighbours aren't the most agreeable) but can anyone recommend an amp to go with the new player? I'd prefer one in silver to match and something quite slim if possible as I've not got a lot of room. Also I'd like to keep the price down as low as quality allows. Any help would be greatly appreciated.
