I am looking to purchase a new amplifier very soon. There are a few amplifiers of interest. I currently have a NAD M2 and Rogue Audio Cronus Magnum, that I will move on. My room is 17ft x 13ft x 9ft. I am considering a Devialet 220 Expert Pro CI as an all in one solution. There are a few other amplifiers on my short list e.g. Sanders Magtech, Benchmark AHB2, Audia Flight FLS9, ARC VSI75 but would like to know if anyone has experienced problems using the Devialet amplifier on active ESL. Thanks.
