Optical recording vs USB transfer

[Sony_Fan]

I was just wondering whether or not there is a difference in sound quality if you record a CD using the optical input @ 256kbps or if you transfer it through USB @ 256kbps. I've heard that optical realtime recording can be more precise. Correct me if I'm wrong.

I don't know if this still applies to Hi-SP but it is probable. The problem you mention is actually referring to 292 kbps (SP mode). Transfering 292 kbps via USB is really 132 kbps with filler to play as 292 kbps. Recording via optical @ 292 kbps is true 292 or "true" SP mode. It is generally agreed that you will get better quality from optical in because the hardware is doing the encoding at true 292 kbps. Transferring via USB means software is doing the encoding at a lower bit-rate.

To be honest I can't hear the difference between the two (Hi-SP optical or USB Hi-SP transferred tracks.) The difference is noticable between true SP and SP mode transferred via USB (Sonic Stage or Simple Burner).

That's interesting, i didn't know that. If there is a difference with Hi-SP (optical vs USB), I hope it's not noticeable. I honestly can't tell the difference between old SP and Hi-SP. I only do recording with Hi-SP, that's why I brought this up.

It looks like the jury is still out when it comes to Hi-SP hardware encoding vs. software encoding.
