Onkyo or Yamaha please help

Hi there i am currently looking to upgrade my Onkto 608 to an amp which has 2 outputs due to a new projector being bought.

I have been looking around and have found the following amps & wondered if anyone with more knowledge than me can point me in the right direction.

My speakers are MA RX8 & RX surrounds etc with BK LS200 Sub.

I have found the following:-

Onkyo 709 (Customer return Re-Con) £619

Onkyo 1008 £699

Yamaha 1067 £500

Yamaha 2067 £625

I also know Pionear are very good so if anyone has any other options around the above price points i would be interested along with any advise on what might be the best from the list above!

Thanks

Andy
