Apple lossless -vs-24/96

In J River, you need to use WASAPI, WASAPI - Event, or Kernel Streaming. Set that in Tools - Options -Audio - Audio Output. If you are using Direct Sound you get the Windows audio, which is usually does not do 24/96. Also check under Audio - DSP & Output Modes to be sure you are passing 24/96 with no change.

I also use this little tool to see how much content there is in a track above 20KHz. You can also use Audacity or other tools for a more precise look at the file. It is surprising how many HDTracks 24/96 tracks have very little content above 20KHz.

Lads - I believe the Wadia 151 supports 24/96 via USB. That can bypass any sound card you have.

Thanks a lot for the info. I thought I was probably missing something from J River. I will try that and let you know!

You probably also want to check the Exclusive Mode box in the Output Mode Settings, right under the option where you set WASAPI. That keeps the OS from trying to break in and bring it back to 44.1KHz.

Thanks everyone for your help! I have been listening to 24/96 files for the last hour or so. I can't believe the difference! I am really amazed to hear 24/96 via usb via my locus design polestar.
