I wasn't too worried about the THX certification when I was shopping for my gear. All I was looking for was DTS and Dolby EX processing. Just audition a few different recievers with the set of speakers you already own (or about to buy), and pick one that you like the most. Pick a CD and/or DVD you are familiar with, and bring it to the the show rooms to test out on all the different combinations of equipment that interest you. If they're not willing to help you audition some equipment, move on to a differnt retailer.

If you're hell bent on THX, I'd suggest doing some research on it. There's a ton of articles online. Just google for "THX certification." Good luck hunting.

What Geoff said. The THX labeling isn't gonna make a significant difference in your overall sound quality like for example Dolby Pro Logic vs DTS & DD, some even say it's more of just a marketing gimmick. Listen for yourself to make the best decision, which is what your ears tell you. Let us know what conclusion you come to, and good luck.

I would say your spousal challenges need more attention than THX certification. I found that my wife was very annoyed about the endless stream of components and upgrades too.

My solution? I practised serious restraint for about seven years and throughout having two kids. Nothing like no disposable cash, decreased salary from spouse, diapers and formula to force the end to my indulgence.

The good news for me is that I am getting a real home theater built into our new house c/ w lots of good components and a huge TV.

The moral of the story? Do you wanna be in the loop on the lastest A/V gear or do you wanna be happily married? Save yourself the aggravation w/ battling about it. Women just do not get this stuff and I suspect they never will.

Hang in there dude ... choose gear that looks and sounds good to you! The good news is that A/V gear has a much longer life span than computer gear!
