Default How to test sound quality on new system hookup?

Hello all-

I recently received a Denon AVR-685s receiver as an anniversary gift, and hooked it up in my living room. I'm not tech-savvy with my terminology, so please forgive me in that respect.

Essentially, I'm working with stereo sound. Back in June, I went to Tweeter, Etc. and picked up a pair of Boston Acoustics CR95 towers, as Tweeter was clearing out their supply of Boston home products (except in-wall applications). A dumb move on Tweeter's part, but I digress.
Didn't have the money for a CRC center channel or a pair of CR65 surround bookshelves and a subwoofer, so stereo it is, for now.

They sat in my garage until the receiver came along--didn't have any other receiver prior to this. I had some 12-ga. speaker cable from Home Depot which I'd bought in July, in two six-foot runs. Got the towers hooked up, and eventually figured out the receiver Menu. I got the DVD player working well (digital video cable), but the TV and VCR produce no sound. Turns out that's because I only have inputs on the TV, no outs, and my VCR is too old. Crutchfield.com helped me out with tech support; basically I need a new VCR. With that, I can produce sound from both, so long as the VCR's turned on. A pain, but supposedly unavoidable due to the TV
(which is a 27").

Here's one thing I'm wondering: is there a way to test my connections to see if I've got the best sound possible? I'm not talking about the "test" feature on the Denon; that works fine. What I mean is, maybe playing with the volume without having a CD in to listen for humming.... or some kind of distortion while I've got something playing..... or something like that?

The CR95s do sound a bit bassier than expected, and something seems a bit... "off." For lack of better expression. I know it's only stereo sound, but honestly that's what I grew up with, so I don't think it's the missing virtual surround that's messing with my ears.

I assume (perhaps incorrectly--you may call me on this if I'm wrong) that if the speakers aren't connected properly, that there would be static or popping or something. Like if a wire wasn't in all the way? All posts are tightened well, though; I'm using bare-wire connection on both ends.

A long description I know, but I had to get the facts out there. Thanks in advance-

Default Get a test DVD - they are about $40. They will help you set up the system.

Default Re: test DVD

Hmm, that looks like video calibration, though.

Default Any other ways?

Perhaps I'll try it, but short of spending $40 I'd rather not spend on a CD (that's a lot), what other approaches can I take?

Thanks.

Default These type of discs are really worth it -

They explain to you all the techinical side of what the disc can do for you in setting up your speakers. Great for a noob or even if you are an expert. Most of the magazine techincal writers for the Audio/video magazines use them.

Default It's a DVD, and if you don't get one you just pissed away hundreds if not thousands on decent gear

that doesn't sound or look like it should

Jeebus. Radio Shack has a knock-off audio version of Avia for around $19 if you're that strapped.
