How do these amps sound and perform (Evo & Evo 2)? I gather Creek are a good brand in audio, but havent had the pleasure myself of hearing any items. There is one 2nd hand Evo currently for sale and one new Evo 2 at a good price i see. I was initially going for a Yamaha AS500 but seeing i can get the Evo 2 for around double the Yamaha, is it worth pushing budget for it? Similar power wise so really depends on sound i think. Also, what are the differences between Evo 1 and 2, similar specs other than Evo 2 can seperate pre and power amp from what i have gathered.
