RE: Let the grenade throwing begin...

Currently the DAC is limited to 96/24 due to the limitations of the TAS1020B USB transceiver. It is only USB 1.1 compliant, while USB 2.0 is required to achieve the speeds required to reach 192/24.

Gordon is working on ways to get USB 2.0 working. It appears that it may require a hardware upgrade, but it is possible that it could be done with just a firmware upgrade. In either case, currently only Mac's OS supports those high sample rates with the native USB driver -- not Windows and not Linux.

In any event the unit will be upgradeable, as the DAC is modular. In the meantime, there isn't much software available at sample rates past 96/24. I think the main use for a higher sample rate would be if one were transferring a vinyl collection. The problem there is that there aren't that many great sounding A/D solutions currently available.

I guess the bottom line is that computer-based audio is still in flux. It will eventually reach a stable state, but all new things take time to mature.
