I have been doing a lot of research lately into this area. Once I get my Eros, then I plan on burning a few hundred jazz albums--many of which cannot be purchased via any medium today. Here is what I have found out. First, there are a lot of 24/92 ADC systems available...some USB and some FW. Many of the better systems can burn at 24/192 and this is the route that I think I am going to go.
One of the cheaper ones, but one that I have read a lot of rave reviews about is the Ross Martin PCM4222 ADC (it is at the bottom of the page). This page...
http://rossmartinaudio.com/index_files/Page318.htmI have been an Apogee fan for years, and I talked to a Sweetwater rep and he suggested that I go with the RME Babyface instead of the Apogee Duet II. That is if I decide not to go with the Apogee Rosetta 200, which from what I hear is a kicker of an ADC. It only has two channels, but once you get the FW card for it then you are in the same price range as the Benchmark ADC. The various reviews I have read put the Rosetta above the Benchmark. I was told that the Rosetta is superior to both the Babyface and Duet, and it should be since it cost twice as much.
