[quote user="matengawhat"]The way i read it is that by reducing the input volume the harder the amp has to work for the same given volume - most amps only work to say 10 maybe 11 before its to loud so not utilising the real power of the amp before everthing becomes overblown so by using them it allows the amp to be more productive and fills out the sound - you can't get back what isn't there because of compression these just allow the amp to breath. Your Dac with work in the same principle by reducing the input volume allowing the amp to breath.
With regards to the compression bit it suggest that as producers turn everything up they have to reduce the dynamic range to fit the waveforms on a cd - get really complicated about now - best thing for the industry to do is turn all the level down and leave the dynamics - once read somewhere that when CDs were first produced not sure if still do - the record companies decided to remove all the frequencies that is was perceived the human ear couldn't hear to save space this left cds lifeless which is why many people still think vinyl sounds far better. If thats a myth i'm sorry but sure read it somewhere many years ago.[/quote]
I thought the only amps to go to 11 were Spinal Tap's ;-) Oh, you mean 10 or 11 as in clock face

Totally agree and answered very nicely. A variable output DAC will do the same thing in effect. However, a decent DAC will cost a packet and you might not like the resulting 'house sound'. However, if you're happy with the house sound of your CDP but suffer from the 9 o'clock volume problem - attenuators will do the trick.
However, your myth about CD may or not be incorrect. I would be skeptical. What I do know is that the first CDs were manufactured carefully, there were many wasted, but to some audiophiles those pressed by certain plants are far better than the increasingly loud and compressed CDs as demanded by the industry in recent years Joe's post refers to.
For example, Genesis Seconds Out (from I think a certain French plant) has a version which is apparently superior.
