Okay, a few people are going to say I am nuts for saying this, but
it`s one of the major reasons for some of its inefficiencies.
THE DISCS ARE NOT PERFECTLY ROUND.
When the discs come out of the factory, they look round,but they are
far from round. This creates a push-pull wobble effect.
I have done blind listening tests with the same discs. One of them is
the factory version and the other is a perfectly round bevelled disc.
I heard information on the bevelled disc which was missing from the
factory disc. Don`t believe any of the AudioFools who say it doesn`t
make a difference. Any person who can hear properly, can spot the
difference right away. It`s amazing, that the manufacturers let this
happen in the first place. Even AudioFool CD`s aren`t bevelled.
The reason, I didn`t answer this question more quickly, was that i
couldn`t find the website for you to see for yourself. The bevelling
machine comes from Germany.
There are DAC`s out there, that don`t use any filtering whatsoever.
Please check out the URL below.
http://www.sakurasystems.com/articles/pitracermemo.htmlThis is a Japanese company, which is way ahead of the game. Instead
of fixing the Digital to Analog converter with filtering and
oversampling, they choose to attack the problem at its source. They
keep parts, in the units, down to the bare minimum to get the job
done.
