I know this sound like a silly question to some people but my 20 year old Sony amp (yes 20 years old) is starting to sound like it needs to be replaced and I've been looking into a range of options. The first is a CA 650a (or a 550a) with a photo pre amp. The 650a with phono amp will cost £400. The second option is a Rotel RA-04SE, which will be £300 and the third option is an Arcam A18, which is £470 if I trade in my old Sony amp. My source is lossless files with a DACMagic and my speakers are a pair of Tanoy Mercury F4s. I listen to a very wide range of music from Coldplay, 80s pop, through to classical. I know that I need to listen to the amps and compare them but this is going to be difficult as I can't take my speakers and DAC into a shop to try them and the 650a is not in the same shop as the Arcam or Rotel. The room I use is just 3m deep and the speakers are next to the wall so I need to pair the amp with care. People's thoughts and help please. Oh the connection cables are Chord Crimson II's. Cheers.
