I am thinking of adding a 5 channel power amp to my HT setup. Currently using a Marantz SR5300. Thus, my SR5300 will become a pre amp. Due to my tight budget, I have narrowed to these 2 amps. I am using a pair of AE Evo 1 for my front and rear surround as well as Infinity Alpha center. Sub is Mirage frx S8. My main aim is good stereo. I usually listen to symphonies with ocassional Jazz and movies. I am not into serious HT thus sticking with 5.1 setups. Thanks for your help.
