I use Roxio platinum version 5 which just has the simple sounstream feature where you can play about with the graphic equaliser. I've only tried it once and although in preview you could hear the difference it didn't seem to make much difference when I burned a copy. It may be you need to be brutal with the settings to make a real difference.

But a friend of mine did a couple of Beatles compilations 1965-70 where he pumped up the bass and volume (I'm not sure what software he used) but wow that did make a difference. Hearing Taxman/Day Tripper/Drive my Car/Nowhere Man etc with a thumping bass drum for the first time. Not for the purists, but I find some early Beatles a bit too thin and weedy. Like I said purists would call it sacrilige but each to his/her own.

Happy to trade if you ever want to hear the effects.

Cheers
Mike
