Vinyl to Digital: Software or USB Converter?


I'd like to digitize my vinyl to play via AIFF. The options are a) to use a phono preamp which outputs USB, or b) to run the preamp output directly into the Mac's audio input and digitize it with Roxio Spin Doctor. Any recommendations on which would produce higher quality recordings? If you recommend the software route, any suggestions besides Spin Doctor?

Under $500 for line level A to D via USB. They use the output from your existing phono pre.

HRT Line Streamer

Korg MR-2

No experience with either of them.
you should check out the Lynx Hilo it is an AD/DA converter with headphone amp.
