Can the toslink connection pass 176? Should I try using the 2-channel analog outs instead?
Your receiver should display that it's getting the upsampled bits. Both my previous 2001 and current Yamaha do. Try turning off any surround, DSP processing, run it 'straight' or 'no effect'. Also try pressing down or display on the remote to see the current PCM sampling rate.
Theoretically 44/88/176 should sound the same. 48k should sound different since the PS3 has to map 44 onto 48 and it's not a simple multiple so the waveform is more likely different. Realistically those 44/88/176 sampling rates make those musical digital bits take a different paths in your receiver allowing you to choose which sounds best/cleanest/least modified. On my previous receiver upsampled was better, but on my newer receiver I have a harder time telling butt I still have a slight preference with the original 44k.
Yes Toslink can pass 176k. Analog outs sound great too according to many including myself who tried it for SACD.
