Good morning Eric,
For stands, I'm not familiar about the best places to get them, because I make all my own speaker stands myself; the reason why being that the stands I really like, cost generally more than my speakers and can go up into the four digits. Oh, don't get me wrong, I know a lot of brands for speaker stands, but I just don't but it. comprende?
So, my best advice to you for this, is to go in the speaker's stand section, where the experts will be delighted to help you.
About your PS3 (did I give you not some already tips & links about that), anyway, here it is: in the audio menu setup of your PS3, it ask you which audio codecs are compatible with the receiver that you are using, in this case the Onkyo TX-SR607; so you simply select all audio codecs that your 607 can handle, which is all of them (I think), so for bla, bla, bla, you select Bitstream, Bitstream and Bitstream again (DD, DTS & ???). From digital Optical output, of course. Resolution, all of them (44.1, 48, 88.2, 96, 176.4, 192khz)
Ok, now, for D TrueHD & DTS-HD MA, because your PS3 does not output these high resolution audio in their Bitstream fashion, you'll have to select also Multichannel Linear PCM.
Eric, you just Select all of them, just make life easier for you, for me, for your PS3, for your 607, for your Mom & Dad, and for all in the family.



* And if your 607 does not handle one of these audio codecs (which it does not) or anyone of these resolutions (which it...), then, it will simply not output it, no harm, no gain, nobody hurt, no one cry, no more, no less, no sweat, no problem at all, no brake up, no injuries, no accident, no nothing or nothing at all.
Any more questions?
Cheers,
Bob
