The SLM-1s are the yorkville monitors under a dif name. I verified this by calling ART myself as they look exactly like the YSM1i. I dont know about the ART amp but the yorkvilles (and the slm1s) are just about the only thing worth looking at under a grand. Their only flaw is they dont go loud...that is the sound loses the smooth, effortless yorkville clarity and balance when you crank the speaker.
