two digitallish questions.

Yes, putting in extra bits might be possible.
I record those cd's via the analogue out of the cdpayer.
This sounds a lot better.
Maybe they just add an extra bit that gets ignored by straightforward DAC's
but frustrates the spdif. As if they send in 18 bits resolution, but 'forget'
to tell the dig out there doing so.
The built in DAC is then converting the most significant bits, while the
digout gets the least significant bits. Just guessing here, but I asume this
gets the signal clipped too.

I really like to *know* what's going on here, see, I can understand
that beat orientated music gets to be clipped, as that sounds nice
on big PAs. I do that myself too.
But trumpets on that sound beyond dirty in Ricky Martin is not
what I expect, especially not when it ~only shows in the digital copy.




[Q2 12Mhz on DAC balanced putput]
Two suggestion have been made:
- ferrite on the wires
- cap over the phase and anti fase wires.
Which of those would you guys suggest?
The tone is the clock of the ADC which 'resamples'(sort of) at that rate.
