As of 6pm CST, I have 7.1 surround sound via analog outputs on a new Panasonic 55k Blu Ray player.

Here are my first impressions:
*** Can you notice a difference between DTS Master/TrueHD vs. the higher bit rate Dolby Digital/DTS ? Absolutely, positively yes. The frequency range is much wider, the bass much tighter and the surrounds are more active. I did have to crank up the speaker levels +5dbs but that was it. Previously, I had been using a PS3 w/ an optical cable.

*** Can 7.1 work w/ your couch only 18" off the back wall? Yes. It sounds great. Just have the distance and delay set properly on the receiver. Listened to "3:10 to Yuma" and 7.1 certainly adds an great enhancement to the rear sound field.

*** Did my wife come in mad because she could hear Opitmus Prime and Megatron battling way out in the driveway? YES !!!!!

My set-up:
2x M22
4x QS8
1x EP500
1x VP150
Yamaha Rx-V659
Panasonic 55k Blu Ray

Nice to hear you're getting enjoyment out of your system and are finding the new gear worthwhile. My couch is currently only ~2' off the rear wall, too, so if I get some benefit from the two QS8s I have on order, that's great. I was really buying them in anticipation of when I have my system in the basement.

Just goes to show how even the "smaller" Axioms (bookshelves), with the sub of course, are pretty darn impressive!

Now, if I could get 7.1 working with my couch about 10" from the back wall, then I'd have to get some more QS8's!!!!

Well I'm confused, just when I thought I was getting a handle on all of this.

I don't understand why you connect through analog? How can it be True HD if its running from analog outputs?

Wouldn't you be better off connecting via HDMI or Toslink?

His player decodes the new audio formats and can send them via analog. Toslink isn't an option for the new formats. His receiver doesn't have HDMI, so I'm guessing that's why he got the player he got.

I will have to find something to read up on, How can it be digital if its sent in analog? Or is it straight analog to each speaker, passed through the amp?

Sorry if I seem a little dumb but I am just ryijng to understand how its done.

Oh, it's not digital. All signals have to become analog at some point. In this case it just happens one step before. If it was sent digital to the receiver, the receiver would be the one converting it to analog.

And no, you don't seem dumb at all. There's too much to know in this hobby, as I'm a very good example of. I have to ask for help quite a lot.

Not dumb at all. This whole thing can be really confusing.

All the audio information on a Blu-ray disc, all those little digital ones and zeros, must be decoded into analog information at some point before the info reaches your speakers. This operation is performed by a DAC (Digital to Analog Converter). It doesn't really matter where, between the disc and the speakers, that decoding takes place. The digital info can remain digital and be sent the receiver/preamplifier in digital form, where it is then decoded, or the DVD player can do the decoding and send the info to the receiver in analog form.

Blu-ray digital audio info, for whatever reason (I'm not tech oriented enough to understand why, but I think it's got to do with the size/amount of info that needs to be sent) cannot be sent from player to receiver via an optical or coaxial connection. It must be sent via HDMI. If you have an older receiver which doesn't have HDMI inputs, in order to enjoy the newer audio formats found on a Blu-ray disc, you must have a player that is capable of doing the digital to analog conversion and which has analog multichannel outputs. Plus, your receiver must have analog multichannel inputs.

I have to laugh at the "older receiver" thing. My receiver is somewhere between 2 and 3 years old and, though usable, is now obsolete. I used the first receiver I ever owned for 30 years. \:\)
