I have the manuals for it. I have to say it is one of the best written manuals.. for any product, ever. If you want to really understand everything there is to know about sound..both analog and digital, this is the book I recommend. Its a shame they went out of business, as the OP said, they made one of the best sound cards of all time. I still record on mine all the time. Its pure class-a quality. No harmonic distortion whatsoever.
