Although i rate the A1 as a very good amp...and ive been more than happy with it for the last couple of years...im looking to upgrade basically for the need of EX, DPL2 capabilities on the more up to date amps available. Now i would love the latest Yam amp Z1 (or whatever it is) but the pennies dont stretch that far...well actually no where near that far ! so.......mayby someone can suggest a good amp say around the £600 mark which will add the extra channels but wont compromise on the sound quality of the A1....note= home cinema use not so much on the music. Yamaha would be probably my first choise but who am i to know ! mayby another make might be better. suggestions ?...speakers in use are the Kef 2005.2 eggs. All the best for the new year.
