integrated or separates...on a $1200 price point?


I am running B&W 685s and a HSU sub in a 2.1 system, and I need to upgrade my 15 year old Yamaha receiver. I have been advised to purchase a high-end integrated rather than separates in my price range, which is around $1200 or so. So I am looking at: Creek 5350SE, Exposure 2010s, Parasound Halo A23/P3 (used), or used NAD gear (like the 2200 power amp). Looking for great sound reproduction across several genres, not all of which are easy to reproduce: rock, classical, some dense IDM, and other heavily layered music. I am wondering if the lower wattages of the integrateds leave enough head room to punch through the entire frequency spectrum.

New I would go integrated.

Used I would go separates but be prepared to be patient and spend a lot of time checking here and ebay for good deals.

Thanks for all the advice. I am still saving up, I don't know how long I can last before I pull the trigger on some new equipment.
I picked up a B&K Reference 5 s2 pre for $400.00, used and a B&K Reference 200.2 s2 amp for $650 used. I think it works quite well with my Paradigms, but don't know how it would do with the B&W, but I imagine it would be pretty good.
The DK integrated are a hybrid and give you the solid state slam with a tube preamp built into one package. A great bargain used.
Separates give you flexibility in mixing and matching while integrateds give you simplicity and convenience in a one-box. The main advantage of separates is when huge power-hungry speakers are used and huge amount of power is required to drive these speakers. That is where massive and heavy power amps and monoblocks come into the equation. If your speakers are efficient and relatively easy to drive, I would say integrateds are the way to go. There are many good quality integrateds these days that can give you comparable if not better performance compared to separates.

With the B&W 685, I would think that a good integrated might fit your needs better if simplicity of a one-box is important to you. Not only you save space for an additional piece of equipment in the preamp but you save on an additional pair of interconnect and power cord.
