I just got mine yesterday and I was a little miffed that they didn't supply the USB A to USB B cable, so I had to run out an get one. For OS X, no drivers, so it was plug and go.

So far, so good. I've been playing around with it with and without Bitperfect.

From the limited amount of info, to take advantage of the apodising filter, you set it at the 44K and it does the rest. If you already have 24/96 or 24/192 files, then you have to change the settings on the Midi setup from what it sounds like. I currently have mostly lossless and compressed files and no 24/96 or 24/192 files, but I'm going to get some to try out.

The front selector only changes the source from USB to SPDIF. I am sure like most audio equipment that a little bit of burn in time might improve the sound, but so far, it sounds great.

They do ship with a power supply that connects to the USB port if it's not being used with a computer and they supply a variety of power plug adapters depending on what country you live in, which is nice. They also include a RCA to 1/8 mono adapter and a Toslink to 1/8 inch adapter. But no USB A to USB B cable to connect to a computer.
