What you want is very low burn-induced jitter. This is not very useful with good CD players, only with very crappy ones you can hear a difference with high CD jitter. If you can hear any at all. This is a very controvesial topic as no double-blind testing has ever proven that there could be an audible difference, ever. Just like the audible difference between different CDR brands. People claim they hear a difference, but when in double-blind testing suddenly they don't hear it anymore.
I think you didn't mean "Gigarec" (which allows overburning) but "Varirec" (which in theory allowed better recording quality , jitter-wise, but I've never seen - or heard any proof of this).
The NEC 4550A and 3540A, both DVD burners (strange!), give most excellent jitter results (steady 7.5%), up to @32X with good CDRs. These are my favorite audio CDR burners, together with high-end Plextors.
The Plextor 740 being a rebadged Benq 1640, and this drive being rather mediocre for audio CDR writing as far as jitter is concerned, avoid it. Also Pioneer burners are not great in this area.
