How about buying the one that you like the sound of the best? ...and offers the features that you want.
		
		
	 
Getting a demo is tricky around these parts, so I'm quite happy to utilise the Distance Selling Regulations 
All the options include the features I'm after.

			How about an Arcam AVR350 for £599 which, quite frankly, will blow your other options clean out of the water without even trying.
		
		
	 
Lack of HDMI is a deal-breaker.
	
		
	
	
		
		
			with what speakers?
need HD Audio/HDMI/scaling?? etc etc ....you may as well draw straws if you don't know what features you need/want.
		
		
	 
Rega Ela's up front, B&W 602S3's at rear, phantom centre (for now), no sub (for now).
HDMI audio is a must. Don't care about upconversion or upscaling.
	
		
	
	
		
		
			Set yourself a budget. Then use Avforums to give you a list of top amps within that range..
then listen to as many as you can. then buy the one you like best.
the only way to ensure you are getting the best for your cash
		
		
	 
Budgets are meant to be broken (or is that rules?). Extensive use of AVF has produced that list.
	
		
	
	
		
		
			I went for option 2, though if I wanted a new amp for sound quality alone I'd go for the Arcam. (but I wanted sound decoding via HDMI & the HD sound formats)
		
		
	 
That's what I'm leaning towards...
The real point here, was to decide whether to listen to my brain, wallet or gut 
I've pretty much decided to let the wallet be damned 

 so it's really just a question of listening to the old noggin, or going with my gut.
