For what it's worth, the CEO of dbpoweramp, who I would guess is also the programmer, verified that
the results shown for his software are correct. I asked him why his software passed those tests so
well. His reply:

" --------------------------
Because we use SSRC high precision as our resampler, it is one of the best.

I _think_ this is the guy who authors SSRC, which is apparently an open-source software tool:
http://shibatch.sourceforge.net/

If I'm not misinterpreting the results, dBPowerAmp is the ONLY perfect conversion software for going
from 96/24 to CD resolution. At its ridiculously low price, it's the bargain of the century.  I
don't know if there are other tests or specs that matter more or less to conversion audio quality.
I'm assuming the guy in Canada who took the time to perform all those tests thought they revealed
audible differences between the SRC's, audible with real music in real studio/production situations.

By the way, dBPowerAmp's CD ripper software is also superior to all others I've tried. I've built a
digital library of FLAC files with accurip verfication quite efficiently using dB's CDRipper.
