I have recently purchased an Arcam CD 73T cd player which I currently play through my Marantz SR7200 Receiver. I would like to separate my cinema surround sound from the music side. I have a buget of around £400 to purchase a suitable amplifier. My speakers are Castle Harlech floor standers. Could someone suggest a suitable amplifier that would do justive to both the arcam cd player and the castle speakers.
