Remote controlled Integrated amp, 50 watts per channel. These were £700 new, now going a bit cheaper, but they are superb, Mf's best modern amp yet, better than the x-a1 type. Brighter, more dynamic and engaging.Clean, powerful sound and runs warm. Top end undoubtedly its strength, very nice. Seriouslyu Sexy build, 4 inputs, totally mint, all unmarked boxes and packing. Can be upgraded via MF to a x150 for £250 extra. I have agonized whether to sell, as its so discrete and WAF friendly, but I need the cash. Serious bargain at £250, warrantee not even sent in.
