I have just purchased some new hi-fi Yahama A-S500 Amp and Monitor Audio BX2 speakers. To sasy i am amazed with the sound is an understatement, but i am using an 10 year old Sony DVPS 7700 DVD/CD player, i know in the day this was an £800 player which had alot of audio playback features built in, but would a dac like Cambridge audio Dac Magic make any difference? or a dedicated cd player at the same price around £200?
