You do realize you'd be getting the EXACT same sound if you stayed with the PS3, and used LPCM. The only difference is that the TrueHD, or DTS Master light will not light up on your receiver because it doesn't have to decode the codec. Decoding the codec is not like a D-A conversion, it's more akin to simply unzipping a zip file. The end result is exactly the same whether the receiver does it or the PS3 does it. The only difference being that the PS3 has faster processors at its disposal, and so may be more efficient at the decoding. This also means less processing, heat, spurious signals, etc., in your receiver, so could possibly result in better sound by having the PS3 set to LPCM instead of Bitstream. I wouldn't go so far as to say that there would be a measurable difference, and under blind A/B testing, I'm sure a human would not be able to tell the difference. I saw you already bought an additional blu-ray player, but perhaps future readers will be spared the expense from the misinformation above, or perhaps you would still be able to return it.
