usb cable

i believe there are several companies that make aftermarket usb cables, with all the necessary connector types at either end of the cable, and at differing degrees of quality, when i had the explorer, i used an audioquest forest usb cable.

audioquest alone makes a few different models.

Any comparison with M2Tech hiFace DAC?

How does the M2Tech hiFace DAC (same price but 384kHz/32bit!) perform compared to the Meridian Explorer? 

Does Stereophile plan to test the M2Tech hiFace DAC?

Another question: can either of these DACs drive a power-amp when connected directly (i.e. with no pre-amp)? 

Thanks for any feedback!

TI low latency filter

Yes, this looks like the 0.55 FS notch of the TI low latency digital filter. The Meridian apodizing filter should have had his notch at exact 0.50 FS.
