Please educate on use of integer mode.

I am using Pure Music on a MAC mini for playback of redbook CDs. THe MAC feed a M2Tech Hiface which feeds a Bryston BDA-1. I wish to optimize Pure Music playback. Am looking for a USB/SPDIF upgrade.

How is PCM data streamed vs. when Integer is not activated?

In this case, the ability to use integer mode in Pure Music is dictated by the USB/SPDIF converter, true? Does the Hiface support integer mode?

Thoughts on having Pure Music upsample vs. use of integer mode and having the DAC do this.

Thanks, Mike
Unless you are still using OS10.6 Integer Mode is no longer available with Pure Music.
