No.

48kHz allows to bring you all the frequencies you can hear, and a lot more that you can't. So going beyond 48Khz, can't give you a better sound. Moreover, in the worsts scenarios could introduce artifacts.

It can also improve jitter from 16/44.1, so yes there can be improvements.

The PS3 via HDMI decodes and upsamples and outputs linear PCM soundtracks of 7.1 Channels at 176.4 kHz. Are there any other players that decode and upsample like this, or are there any receivers that upsample lossless audio bitstreams to 176.4 kHz or even 192kHz?

I'm not trying to start a standalone vs PS3 war, or a bitstream vs decode debate. I'm simply trying to see if there are a) any improvements by upsampling, b) other players that do this, or c) other player/receiver combinations that offer higher audio resolution.

It doesn't upsample 7.1 tracks to 176.4, it outputs them at whatever the resolution of the source is. A 7.1 24/48 soundtrack is output at 24/48.

It can upsample 2.0 CD 16/44.1 tracks to 176.4Hz, but it's only 7.1 flagged on the receiver if you have the 7.1 output checked, it doesn't actually output 7.1 - it's still outputting 2.0 stereo.

When I listen to a CD on the PS3 I uncheck all the 5.1 and 7.1 options so that it correctly flags 2-channel stereo, thus the receiver doesn't send a blank static signal to my other speakers.
