the phillips and sony machines were the first i'd heard late '82/early '83 at Pacific Stereo. i liked the sound of the phillips better [warmer] but the sony had real alphanumeric display while the phillips just had red LED lights.
When CDs first came onto the market in 1982 .......
Everyone was "blown away" with the perceived clarity of sound.
I might be wrong (hence this post) but my recollection was the major difference between a CD and it's vinyl analog was merely volume.
CDs were mastered with an audio stream turned up to 1.2v (?) whereas all analog recordings (vinyl, tape etc.) had been mastered using an analog audio stream of 0.8v
Is this on the money or am I mistaken ... ??
