LP to CD transfer question...what is best?

I want to make unbelievable quality cd's of my lp collection...what is the best way? Currently i do well with my Pro-ject & channel islands analog rig into an M-Aduio 2496 pc card..my tower even sits on a vibration removing maple and brass spiked platform. Still i'm not producing cd's of the quality i want, yet when i listen through my monitoring headphones the dynamics and huge bass are there...so i think the music is on my hardrive good enough but even when i treat my blanks with mapleshade records Mikro Smooth & burn at 4x the dynamics are a bit lacking. is there such a thing as a high end computer cd burner?

Should i abandon the pc altogether and go with a standalone?

What about A/D converters...are those still around? I hear one may be necessary to get the dynamics i want.

I use WAV repair software for the transfer...it works really well.
