Ok few points there are a few additional points I would like to make.
1. I want to reemphasize how impressive my cheap 12" power sub sounds. I've never been able to go out and buy top of the line stuff and nor can my family but I've been greatly pleased with my Cambridge Soundworks equipment and the BassCube12s has never sounded so good, even with my Harman.
2. As for cheap build quality. Ok I concede. The plastic front dash, the weight and feel, they just don't compare to Harman. But quite frankly, it's not like this thing is going to be running laps. It sits on a shelf, and provided I don't get an earthquake, it won't be moving anytime soon. Plus from a distance of 12 ft, I can't really see the dash any more than I did with the Harman. As such, it's a complete non factor for me, as long as it puts out good sound. I'm guessing if you want to get a more metallic build structure you'll have to look upward in the model lines.
3. Bass/Treble fine tuning....I'm no Audio wiz and when it comes to equalizers I just look and stare at the bar graph looking at the pretty patterns one can make. I haven't a clue as to what you can actually achieve with them. So I steered clear of it after the auto calibration and I went searching to tune solely the bass and treble on some inputs, but apparently on most if not all digital inputs this is not allowed. To do the tweaking, you apparently need to enter the manual settings of the machine that allows you to tweak the Dynamic EQ if you so choose. Since I previously stated I freeze like a deer in headlights at the sight of and EQ bar, I've decided that I will let the computer do the tuning.
4. LPCM sounds fabulous from the PS3. Tested out a few games, Resistance, Uncharted: Drakes Fortune (for those non gamers out there with a PS3 - rent this game, it has a wonderful story, beautiful graphics, great music score, and plays better than the last Indiana Jone's movie). On Battlefield: Bad Company I got some crackling from the surrounds. It's the only game to do so, so I suspect it a game related, not receiver related issue. I will play more with it later. Now I just need to get some great audio BR's to test out. That was the whole point of getting this receiver wasn't it.
Oh and for those interested: I'm running a monoprice 15' 24AWG from the PS3 to the receiver. A monoprice 10' 28AWG from the HR21-700 to the receiver. And to the TV a monoprice 10' 28AWG from the receiver. The longest run is 25' of HDMI without sparkle or issues.
