Just my opinion
Combine the good looks of a Denon and the good innards and price of the Onkyo/Integra and you have the perfect unit for most home enthusiasts who don't make 7 figure incomes.
I think the Integra has some nice internal components. I think it has a fantastic price that will help bring back a lot of people who would prefer separates but don't own controlling shares of a fortune 500 company.
As much as I really think the Integra is a fantastic find - I wish they had gotten rid of the gaudy silver knobs and buttons, hidden some of the inputs with a flap or something. Lastly lose the slanted display - makes this fantastic unit look cheap.
You could get the Onkyo brother of this unit (PR-SC885P
http://www.onkyopro.com/model.cfm?m=PR-SC885P&class=Preamplifier&p=i) which addresses the cheap look of the chassis but instead introduces a green display with the slanted font - won't match any other unit in your cabinet.
Aside from the looks that remind me of the units Sears sold in the 80s, these units have a LOT to offer at a very reasonable price - all in all well done. (maybe next year you can hire someone who doesn't live in a trailer home to design the chassis and the display though - otherwise they'll probably just add flames to distinguish next year’s unit).
I'm a big fan of Denon but their choice in components this year is getting me to seriously look at alternatives and this unit is HIGH on my list. I'm hoping Audioholics will consider a shootout comparison of a similarly priced Onkyo to a Denon - I'd like to know for sure which would be a better choice. I expect both to have some advantages in different areas over the other but it would be nice to know which unit excels and where. Frankly I'd like a comparison of this $1600 to the $7000 Denon coming out - I'd like to know if the price difference would be worth it for me to consider.
