This is more just FYI. I haven't heard either of these units, but Sony just announced at Home Entertainment 2003 (in S.F.) a replacement for the 777es, the SCD-XA9000ES. According to Stereophile (September issue), it will have even more DAC's (18 in all), new styling, as well as (a first), a new multi-channel digital output link via FireWire (IEEE1394). This would allow you to use it as a transport and connect it to an external DAC, do some post processing, etc. Although I know know how many DACs have iLink connectors for multichannel audio. I'm sure they will start building them now.
