thanks Tim, Do you mean that W4S DAC2 accept 16 bit and upsample it to 32 bit? Still I get bit perfect out of DAC?

I use BitPerfect with macbook air Lion and W4S DAC-2 No matter what is the sample rate of songs I listen BitPerfect shows 32/44.1 in status bar. Is this normal or should I tune something up?

Hi Tim, I was reading CA for a while trying to build a system, now looking for software I can use with iTunes. BitPerfect is just what I was looking for, thank you for a good piece of software! The lack of Integer support under Lion was not a surprise for me: Name: Wyred 4 Sound 24/192 Usb Interface UID:W4SUsbEngine:0 Device Id: 54 Default: YES Selected: YES Complex DAC: NO Integer Mode Capable: NO Thus, I'd like to know if BP is going to issue a patch for Apple USB driver or Lion and if this issue is going to be resolved by BitPerfect at all?

Hi all, I'm planning to listen 24/192 which is possible using iTunes, thus mac mini output is limited. Could you please clarify if I should use any of these interfaces to bypass mac mini's output limit which is 24/96? I was thinking about buying Nova/iNova but seems like I'll be limited to mac mini USB and optical output if I don't use any of these devices? Or I can simply connect mac mini digital out to iNova and play naturally 24/192 bypassing mac mini limit? Thanks in advance!
