ronhjuyfg:Even the most basic hifi's can have a fair crack at the mid-range, it's the bass and treble that they struggle with. most high end amps dont even have tone controls as they dont need them and the extra electronics degrades the signal. Ge's are worse cos they have more electronics and they usually need an extra interconnect.
It degrades the sound as much as having the light on the CDP - a lot manufacturers recommend it's switched 'OFF' because it enhances the SQ. In my view that's rubbish, I can't hear any differnce with my Arcam, and I've a pretty sharp hearing.
Tone controls may degrade the signal, but not enough, in the average room, to really notice.
