Burn CD-R from RAM or hard drive?

What is the best way to burn CD-Rs for optimal sound:from RAM (Quick Copy) or back it up on a hard drive first?Aslso,what is the best sounding software available for burning discs?I have EAC and Nero 6 but read that they are far from the best.Any advice would be appreciated.
If you burn to hard drive and use exactcopy software you wont have any jitter issue as far as I can tell.
The key IME is to get a good rip to the hard drive and then burn at as slow a speed as you can stand. I use EAC to rip to the hard drive and Nero or EAC to burn.
I've been using Nikturner920's method for years, and there is no difference that I can tell between the original and the copy.
