I wish to add that, compared to my 96 kHz DAC, when I enable BitPerfect, I hear brighter, more clearly defined percussion, such as high hats, cymbals, snares, bells, as well as strings and other high frequency sounds. BitPerfect sounds more clear than using just my outboard DAC alone. Perhaps it's due to BitPerfect's sample rate conversion and/or all it's refinements. Seems like a better audio engine than iTunes and Mac. You can easily do listening comparisons yourself by disabling, then enabling BitPerfect on the same segment of music.

Wendy please this is the only way i can get in contact with you,you have helped me before to get volume logic back and running by having itunes launch in 32 bit mode,but now with the latest itunes 11.0 release the app is now only working in 64 bit mode,thus disabling volume logic once again since its not a 64 bit plugin and never will be. i just dont understand why the newest version of itunes wont even launch if open in 32 bit mode is checked off,i mean why is it still an option in the get info settings if it doesnt work anymore?? stupid apple. But anyway if can find any possible workaround to get our beloved volume logic plugin working as before as with all previous versions of itunes up until now. i would be willing to actually pay you for a solution. I thank you very much for your previous solution that has given me years of volume logic use!! Feel free to email me anytime @ ilovecocoakrispy@yahoo.com The developers of volume logic should really make a come back and make the plugin 64 bit and charge a reasonable price for it on the mac app store and many many users would be thrilled. why would they ever go out of business?? All other plugins simply dont work well or have ridiculous presets that sound too bassy or too much treble,i refuse to use any of them bc i know volume logic is superior in every way. thanks again wendy!

True, but have you bothered to find out what iTunes settings need to be disabled or tweaked to ensure bit-perfect output? For that matter, spend 10 minutes looking into what benefits features like automatic sample rate adjustment, hog mode, and integer mode provide, and which pretty much any audiophile-grade player supports? If you're going to keep trolling all these apps, at least get informed or, if you have access to some secret knowledge the rest of us are lacking, back up your ridiculous claims with some evidence or explanation. Your first claim requires qualification, and your second claim is simply false. Go away and stop clogging up these pages with your nonsense.

What is iTunes' own "Sound Enhancer" feature for, then? (Preferences -> Playback)

the iTunes "Sound Enhancer" (and every other audio processor / filter claiming to "improve" sound by fiddling around with it) is probably the exact opposite of what BitPerfect is claiming to do.
