A to D PC converter Lynx L22 or RME 9632

I am looking to digitise some of my LP collection. I run WIN7 and have a full size computer with ATX board, etc.

I already have an outboard DAC but it does not to A to D.

Anyone have experience using either of these cards for converting analog (vinyl playback no CD) to digital?

I am not interested in the D to A performance, only the A to D results.

I have searched a lot but most people only talk about the playback performance, i.e. D to A.
