Oh man! This is driving me nuts!

Now there's 3 AV to choose from: Onkyo 605, Pioneer vsx-1016, and Marantz SR5001. Yesterday, the store where Marantz sr5001 is sold offered a discount that will make it the same price as the Onkyo 605 in another store. On the other hand, Pioneer 1016's tag remained the same which is approximately 8% cheaper than the other two.
Though I am impressed with Onkyo 605's latest features, I've noticed from my friend's (Onkyo) receivers that it has HIGH heat dissipation, which worries me regarding the lifespan of its (semiconductor) components. And to as fmw said, their are these clicking popping ticking sounds. As for Marantz SR5001 & Pioneer VSx-1016, they're arent negative feedbacks/rumors' so far aside from the factory defect which fmw shared earlier.

Most of my past time are spent in listening to MP3/FLAC (grunge like Nickelback, techno/house, progressive rock, rap metal, hiphop, rnb) from my PC or CD player. I'm also a PC gamer at weekends. Yet, Im looking forward to purchase a nice plasma TV and a good DVD player (and perhaps a Blu-ray player).
Yes, it's all up to me to find out. But which of the those 3 will be the best buy?
Btw, here is my initial plan for my first system

. I'm excited to hear for more suggestions/opinions.
Main (floorstanding): Monitor Audio BR5
Sub: choosing between Velodyne CHT-12R or REL Q150MK
A/V: onkyo 605, pioneer vsx-1016, or marantz sr5001

CD player: NAD C521 BEE
Once again, thanks a lot nice guys!
