NOS DAC's without any digital filtering?


How are these DAC's able to perform as well or better than DACS that use filtering to diminish aliasing effects? I understand that there are some who believe that the best sounding DAC's in the world are NOS/non-filtering. How is is this possible?

Oops! You guys got me. But I agree, I am often amused, and sometimes annoyed, but I know it's just in fun...I think. He sometimes has some off the wall comments, but I guess it would be a duller place without him.
Keep up the good work Ebm!
Hi, I was looking for a technical explanation rather subjective opinions. Bombaywalla was the only one to do this. Guess I wasn't clear enough. Thank you, Bombaywalla.
Bombaywalla, I think the confusion was....

when I mentioned "aliasing", I actually meant the "pre-ringing" associated with steeper filter slopes from lower sampling rates (ie. 44.1khz). I thought this was same thing. I have heard hi-res tracks from several different companies and the vast majority sound subjectivly better to me, and I assume that this perceived difference has to do with "pre-ringing".

What I'm getting at is...

does a redbook only NOS dac use a different method to reduce this ringing, or does it just compensate by providing [i]overall[/i] better sound somehow?

Of course it's the overall sound that actually matters, I just want a better understanding of WHY.

Thanks!
The fact that R2R DAC is used in non-oversampling mode doesn't mean that
it has to be redbook (16/44.1) only. You can simply feed it with 192kHz and
it will update output at 192kHz. No filtering or interpolation.
