RE: Absolute level of CD during play

Hi
Who said anything about "perfect", what i am talking about are the things that allowed a portable CD player to be made and the mechanical basis of CD and DVD players.

Besides, what perfect is, is in the eye of the beholder, if any format can reproduce a complex musical passage that can be recorded and replayed to make a generation loss test, then clearly, the more generations it can go before being "bad" the closer it is to perfect. Perfect has no generation limit.

" how come all these tweaks like level CD playing work? Scattered laser light, stabilizing the disc, isolating the CD player, the Green Pen, CD fluids. Do you think people make this stuff up?"

IF they all work, regardless of which domain they act on, someone actually did have to make all those things up. Someone really had to think, what can i do to make this work better?
Modern devices are not as easy to "fiddle with the workings" as in the old days.

Open to experiment?
Play a CD through one speaker that you have moved to a distant room.
Have a friend play a good test cd of your choice and when it's at a good listening level, text your helper and tell them to start tapping on the CD player's case in increasing intensity...until you hear anything different.
Then ask how hard were you tapping on it then.
CD players are normally not microphonic like record players are, they do not pick up room sound unless it's bass that's so strong they mistrack.
