Sony BDP-300 and PCM

[Man-Is-Obsolete]

My setup is as follows: Sony BDP-300 to Yamaha Rx-v661 to Sony KDS 50a2000, all connected via HDMI. Speakers are Klipsch Quintet III with a Polk sub.

When watching movies I don't notice a big difference between PCM tracks and dolby digital. I was told there is a night and day difference, but i am not hearing it. Is there some settings I should change on the player and or receiver to fully get the experience. On the player's audio settings there is an option to do auto or pcm. I have it on auto because that will bitstream DD and DTS which the reciever can decode and still send, at least i think, PCM.

Thanks for any help.

There is a large difference between the two, only thing i can think of is maybe your speakers cannot resolve the difference. One question, when you select pcm in the movie menu, what does the receiver display say?

Hi All. Unless U have these config,,,,U wil not hear much diffirence.
(The RX-V661 is a 7.1-channel receiver that, according to Yamaha, can deliver 90 watts to each channel. It offers the usual assortment of surround-sound processing modes, such as Dolby Pro Logic IIx, Dolby Digital, Dolby Digital EX, DTS-ES, DTS Neo:6, and DTS 96/24. Note that it does not have onboard decoding for any of the new soundtrack formats available on HD DVD or Blu-ray--such as Dolby TrueHD or DTS-HD Master--so you'll need to have a player with onboard decoding to take advantage of the superior sound quality offered by these new formats. Alternately, you can set your player to send uncompressed PCM audio, which the RX-V661 can handle)
With the Upgrade S300 player to S500 and 1.3 HDMI you will deffinitely can enjoy High true HD sound(No mater DD/DTS).
BTW. Try some more Blu-ray movies see if U can hear better.(No every movie is recorded the same)

I always heard that even with HTIB speakers there would be a large difference and getting better speakers will only improve that. I know the speakers I have aren't the best but they are better than HTIB for sure.

So will setting the player to PCM rather than PCM will that create the difference? My receiver doesn't decode any hi res audio and I was under the impression that PCM doesn't need any decoding or is that untrue?

Ok so I got home and set the player to PCM instead of Auto and it is heaps better. It is weird though the Dolby digital track is a lot quieter than it was previously but after volume adjusting the PCM sounds far better. THings are a lot clearer, I am not very good at doing A and B tests but to my ears the PCM definately sounds better now.

Why is it that the player has to be set to PCM in order to correctly play the PCM track? When it was on Auto the receiver still showed MPCM but didn't sound noticably different from the standard DD track and the volume was the exact same.
