I have the Ayre 7xe....it's plenty powerful for all the speakers I've heard it with. That includes Focal, Vandy, B&W, Legacy, Dynaudio, Paradigm and many others. You should check it out if you can. I personally feel the Ayre is the most natural/tube like. Very strong throughout the whole band. The MF isn't my cup of tea, but you may like it. Powerhouse for sure, but lacking some of the finess that I hear in the Ayre and the Hegel. I have now heard the Hegel in two systems and it sounded very different. Don't know why, but it did. That's why I am now driving hours each way to NJ from CT as I trust John at Audio Connections in Verona, NJ. I know he sells around the country. You may want to give him a shout as he also sells Rogue and AR in addition to Rega, Music Hall, NAD and Ayre. He knows what goes and what doesn't. He also sells a ton of used gear and much of it is newer and in great shape. If you have another vendor who has been around a long time, use them, but I'd deal with a store owner as they won't play games with you most of the time. If you find one who does, please let us all know, lol.
