H2o, thanks for that, man. From the guide "To take full advantage of the PS3's DSD Disc playback, you'll need a receiver which can process audio over HDMI, a feature usually found in higher-end equipment. HDMI-passthrough is not the same. If the connection between the PS3 and receiver is HDMI, the PS3 converts the DSD audio files in realtime to 24-bit/176.4 kHz PCM and sends it to your receiver. If using a S/PDIF optical connection between the PS3 and receiver, the audio is sent to the receiver as 24 bit/88.2 kHz PCM".
So, as stated previously, I think the new Sony 5400 sacd is the only Sony that outputs at DSD frequency through it's analogue out (2.8MHz). Not sure whether the Vaio's (with Sound Reality chip) convert to pcm or not.
kindms- thanks for your kind offer.
