Apogee Mini DAC: Connection questions


I have recently purchased an Apogee Mini DAC. It sounds incredible. I bought the non-USB version and am connecting it to my computer via a U24 Waveterminal card. I have a couple of questions:

1. Would I get a better sound if I purchased the USB card unit for the Mini-DAC? Or is the sound better going from a quality external card like the U24.

2. I am currently using a glass toslink to connect the mini dac to my waveterminal. I have heard people say coax is better, but others have said toslink is better when computers are involved. Any insights?

Thanks.

USB is ok, but I suggest purchasing a studio grade card for the pc. PC cards have different digital output settings for consumer and pro grade equipment. In one of my applications I use the Digital Audio Labs CardDeluxe with the Mini-Dac. The rca connection on the card is very good, but the balanced option is much better (excellent option if you have a tight budget). This type of set up is the right way to go if you add DSP sampling to output 24/96/192KHz. If you do not plan to upsample, then I highly recommend using the USB option. I have not found any sonic difference from using the USB port on the rear of my pc vs a soundcard usb option. What you might want to consider is using a firewire output off the pc and reclocking with something like the Apogee Big Ben. This option has worked very well for me in my home studio.
