What's with my ears?

[blushiz]

Well, I now have an Onkyo 805 along with two Polk Monitor 50s for the right and left channel and a Polk CS1 for my center. When I got my speakers, I first plugged them in on another TV with a cheap $200 5.1 receiver and the sound amazed me! The acoustics and highs made it sound like I was actually there listening to the music from a stage set. Then, I moved my speaker setup to my REAL receiver, my Onkyo 805. I thought the sound would be breath taking, but it sounds kind of blunt. It's clear, but it doesn't have the acoustic and high ring affect I love so much. I remember when the drums tapped with tension and the cymbols clasped with a ringing high, crisp after affect, it was so damn nice. Now, it's blunt, and that's after Audyssey as well.

Is it my ears, my setup, or what? I had this problem when I first got my $159 Yuin PK1 earphones (rated #1 earphones, almost equal to the quality of high quality headphones). Everything went from acoustic to harsh. Now, My Yuins sound excellant and it makes all others sound like cheap garbage. I'm just wondering, is it my ears or what? Maybe it's my room? My room with the Onkyo 805 is a lot smaller then the one I originally tested it first with. My speaker cords? The receiver downstairs was using monster cords (big fat white ones), my Onkyo is using Walmart brand. Can speaker wire quality really have an affect on how the speakers render the music? I thought it was just more power. Argh, this is so annoying. To my ears, it hardly sounds like an uprade from my tin can Sonys. Maybe my ears aren't trained for surround. I find that hard to believe though considering I own a Macbook Pro, Yuin PK1s, iPhone, and an Alpine set for my car (all of which are known to render quality sound). I'm confused.
