In Reply to: Re: Some thoughts on filters posted by Charles Hansen on April 21, 2004 at 19:53:30:
This all started whith I comment I made about the AN DAC ONE.1x signature which does use an analog filter:
is that the ringing in the analog filter always happens *after* the
transient, while the ringing for a digital filter (assuming the use of
an FIR filter) will be equally divided between pre-ringing and
post-ringing.This latter is because the digital has no phase shift. Now this is
normally touted as a "good thing". But in truth it is probably a very
*bad* thing, because in nature there are always effects (ie, echoes)
after a transient, but *never* before a transient. That is, a digital
filter *by definition* will sound unnatural.>Now this makes sense, because besides a whole lot more music and a huge soundstage, what I hear from this DAC as compared to others is clean, nonfatiguing transients, with a decay that is not "clipped" right after, and not "smeared" at the beginning. It might not sound like a good turntable, but it really sounds more like a good turntable, so when you said...
to make a practical system such that any theoretical problems with
out-of-band energy are probably no worse than the out-of-band energy
found on LPs when played back with MC cartridges. Therefore, the
system compatibility of a non-OS D/A shouldn't really be much of
a problem in practice.>...it "rang" true to me.
Nice post...thank you,
