>> What should I know (other than the Bel Canto DAC3.5 about to be released and the use of the Bel Canto USB link for USB to SPDIF conversion)? <<
Perhaps asking BC about this unreleased version would fill you in better.
I can only say what I know about the current version, as that is what I own. Several mags have reviewed the Â$500 USB to SPDIF converterÂ, AND IN SOME ARTICLES SUGGESTED COLLATERAL MEANS for this conversion. IÂve seen a few, ranging in price from $100 - $500, and if a sound card of sorts is used, a lot more! IÂve also noted as that interface to the DAC 3 improves, so does the resultant audio . And with such conversion from USB, you gain more flexibility with regard to the file formats bit rate and word lengths.
Check the archives here for the DAC 3 info & reviews on it. Usually info on as yet to be released products only the manufacturer can provide such a thing if they choose to.
