Quality of laptop for use with Dac.

Good evening all.

I was just reading a review of a Belconte DAC ( im not actually after a new dac but was reading it simply out of interest) and the reviewer made comments about a possibilty of higher sound quality with a better driver, than the native windows driver, and higher quality laptop as the one he used to review the equipment was old.

Im quite a novice to Pc audio, having recently acquired an AMR processor which is a cd player with USB input. Ive been using the USB with an old, but extremely reliable HP laptop. The DAC inside the CD77 sounds really pleasing, using J River. Owing to the age of my laptop I cannot use some of the recommended output options, one being ASIO.

Is there any sense of what he is saying? I thought is was digital signals that are going to the DAC? I always take what reviewers write with a pinch of salt ( though interesting to read) as almost every component that they review performs well beyond its price.

Anyone have any knowlege that might give novices like me some pointers.

Thanks. Regards. James.
