Get a used Bryston 4B on Audiogon. It will drive 500+w @ 4ohms. Thats what I have. It has a 20 year warrantee so even if is somewhat defective...sent it into Bryston and they will replace all the parts as long as its within the 20 year warrantee. I have Bryston's coming out of my Rotel Surround receiver pre-outs. Thats how I plan to run my possibly future Maggies MG12. As with Maggies the more you feed power the more headroom and more resolution at louder levels. I know someone with 125w@8/300@4 ohm amp that clip at loud and strong passages on the Maggies say anything past 80db. Mind you the Maggies usually trip at 90-95db.
But Masa doesnt drive his Hales with the Elite. He uses his Adcom amp.
