dBPoweramp can be set up to various levels of accuracy, from "Yeah, I'm pretty sure it's okay on the first run", to "I WANT THIS CHECKED 18 TIMES TO MAKE SURE EVERY LITTLE 0 AND 1 IS THERE! AND THEN CHECKED AGAIN!!!"

I use DBpoweramp too.  My above comparison with both formats was using DBpoweramp on the highest level of accuracy.

In other words, ranging from

"Naively overconfident and stupid"

to

"F--- OCD and on prescription sedatives".  :roll:

-----  I did blind A/B comparisons.  AIFF beat FLAC on my system to my ears
My experience.  Potential technical reasons for this - I don't know.

Curious -- could you share with us, what did you hear in AIFF that was lacking in FLAC?

A bit more detail and resolution.  Not night and day, but noticeable.

I read dbpoweramp does not use genuine .aiff, but rather a "pseudo" aiff.  :o

I'm now using a Modwright Oppo Sonica DAC.  Again, I have no idea what the technical differences are.  But it's a 15 minute experiment to rip the same disk in FLAC and then in AIFF and have a friend flip back and forth blind.  Done.  Hopefully FLAC wins as it does take a lot less space.

Could you do a small favor and try a WAV file and tell us what you think?

Not for a while I'm afraid.  I recently moved and all of my ripping stuff is all packed up.  I think I might have tried it already, but I don't recall.

Previous threads and their results:

http://www.audiocircle.com/index.php?topic=139572.0

http://www.audiocircle.com/index.php?topic=103168.0

Out of the many forums and hundreds of threads I've read for this topic, the results have been:

1) No difference detected

2) Among those who detect a difference - preference for the uncompressed (usually WAV) over the compressed (FLAC, ALAC).

3) Occasionally you do find a minority that prefers the compressed over uncompressed.

Typical descriptions: WAV sounds more open, 3D and dynamic. FLAC can sound more closed in and controlled (especially in the bass region), but on some systems this can come off as cleaner sounding which may explain the small minority's preference for FLAC. Again, I have to reiterate that any potential differences are solely based on byproduct noise (patterns - constant noise vs. intermittent peaks) of the processing (CPU and I/O).

FLAC consumes slightly more CPU than WAV for decoding. However, the I/O for WAV is bigger: http://thewelltemperedcomputer.com/KB/WAV-FLAC.htm

I don't know how it is for BDP-2 or BDP-3, but BDP-1 accesses the hard/flash drive in MPD every few seconds while playing.
