In Reply to: So what's the deal with CD demagnetizers? posted by geoffkait on November 8, 2015 at 14:55:08:
CDs contain digital DATA. As in ones and zeros. Period. The transport's sole job is to read that data. Period. And redbook CDs are designed with lots of error detection and correction--of data.
It's the DAC's job to convert the digital data to analog audio. DAC's are critical; transports are not. Any properly-working transport is as good as any other.
We've all used CDs for data. How many errors do you get? And the error detection and correction on CDs is more robust than that on data CDs. In fact the standard for redbook CDs is that on an otherwise perfect CD you can drill a 4mm hole anywhere and the disk will play perfectly. I've seen that demonstrated.
I think the reason that demagnetized CDs sound better is that the person payed for the demagnetizer.
Seriously, the magic happens--or not--in the DAC. The transport is just a digital data reader.
