I had a pair of MG3A, that I was driving with a stereo pair of Audio research D-115MK2. Your talking 115w x 4. 1 stereo amp per speaker. This system kept me happy until I purchased Rowland mono blocs ang Apogee Diva ribbons. The ARC D115 can typically be purchased 1000--1300.00. Hope this helps, happy hunting
