i noticed that the HK was overall better in terms of sound, it ratteled my kitchen table where as my ONkyo does not, lol PLZ dont kill me over that.
the onkyo has another problem that is killing me. when i play games on my ps3, it gives a blue glaze on the dark shades, i got new HDMI as well but thats not seem to work also some times i notice a lag. my point is that with the hk that would not happen.
i dont know what to tell u guys, i think i am just selling cuz i prefer HK over any other brand. thats just me.
or i just like to sell stuff and buy stuff and sell that stuff and then buy other stuff and then sell that stuff. lol. u guys should see me with my cell phones.
If your playing stuff direct and your settings match then there will be no audible difference between the 806 and the HK amps.
Proper Speaker/subwoofer placement, crossover settings are all things to adjust inorder to improve sound. Most folks have their mains set way too low on the crossovers.
Also the difference in power between the 254 and 354 isn't audible.
Plus the 806 is still a more reliable alternative when it comes to working with hdmi devices.
If you want a real upgrade in power I suggest the introduction of pro level yamaha amps.

They are stone quiet and have way more power than a receiver.
You could start with a single one for the LR channels and then add another for the center.
If you don't mind fan noise or are willing to mod. The Behringer ep2500 would be a superior option.
The benefit of this option is it allows you to use EQ's to tweak the sound to your liking.
