I'm with Bob_B. you usually do get what you pay for.
I'm hard pressed to believe one can make up for some lack in the processed or preamped signal by adding better amplification downstream.
My preffs in HT are different than my preffs in 2 ch. as well. For HT I look towards the upper half of the line up. usually settling for a step or two below the top O line receiver/processor. Same with HT amps more often than not. Mostly due to the price/cost of HT than anything else. Multiple speakers, sub (s) cables, amps, etc.
Given that, once I get used to it all, I tend to look to upgrading things, so some flexibility must be attained early on in the reciever or processor, or that road is a cul de sac
AS much as I'll want to continue to upgrade my HT deal, it carries far less priority for me. So very good there is good enough for me. Very good IMO starts up front. Regardless if it's HT or 2ch.
