External DAC for Sony PS3

Note: This was also posted on the Home Theatre forum.

I own a Linn 2-channel (stereo) music system that is in the same room as my 50-inch HDTV plasma TV. While saving up for a true home theatre set-up, I would like to use the music system for better sound when viewing movies on my plasma.

Would anyone know if I can connect a PS3 to an external DAC like the Benchmark DAC1 (digital optical connection) and in turn connect the DAC to my music system (analog RCA)? This would allow me to "see" the movie on my plasma via HDMI and "hear" the movie via my music system (volume set to off on the plasma).
Yes it will work. The PS3 also does a great job in this configuration used as a transport. A good prepro would do a great job as a DAC as well with the PS3.
Funny, I can post a response here imediately, but with this forum it all has to get approved. WHATS WITH THIS AUDIOGON?
