Sony STR DG820 and LFE?

[Raikirik]

I was wondering if the Sony STR DG820 applies the correct boost to the LFE channel. I've been reading all over different places and getting different views on whether a SW+10 +15 option is necessary and I usually don't know whether they're talking about it being through an analog or digital connection. Also, people have been pointing out receivers that do/do not do the boost correctly.

I have it hooked up to an older PS3 via HDMI and my only option is to use Linear PCM for the newer codecs. The 820 has an option to give SW+10 for PCM only via HDMI, why is that? Would that mean if I were to bitstream from a blu ray player that I cannot get a boost? I'm really confused on the matter.

I also read somewhere that PCM doesn't get boosted so I tried watching the first Transformers DVD, switching between PCM and Bitsream since it has an older Dolby track and I didn't hear a difference.

I really don't know what I should be setting the receiver to. If I put SW+10 the bass is overbearing. If I don't, the bass becomes too light and if I were to increase the SW level under the level menu it would have to be quite a few dbs higher than the rest of my speakers.

On another note I read that setting the SW to AUTO would enable it depending on the frequencies present. If so, is this the boost that's supposed to happen? Even then, this is still only for PCM.

Can someone please help clear this up for me. It's been bugging me for quite a while!
