Just thought I'd reiterate what most of us already know.
I've spent the last few months ripping all my CD's to a PC hard drive. Naturally, I've been using the built-in soundcard on this PC to listen to the lossless WAV rips and, eventually, the Ots encoded files using Ots AV. I had gotten used to the sound, which was pretty tiresome and uninteresting - even with the Ots processing.
Well today I have moved everything over to a modest sub-£200 second hand laptop with a modest, quite old, Creative SB Audigy 2 soundcard. The difference in the quality of output is simply amazing. I am using the same software (Ots) and the same speakers as before but it sounds like I've moved from a bathroom radio to a quality B&O living room system!
We say it all the time but anybody who is using a computer to DJ will notice a huge improvement in sound quality if they use a dedicated sound card instead of the built-in outputs. A quick scan on eBay shows most of the top quality cards (internal or external) are available for less than £100.
