I have to agree with yugalg9. I purchased Magnepan 0.7's more than a year ago and after two months trying out different placements and room acoustic modifications they sound more like a live orchestra in a concert hall than a pair of Sonus Farber speakers costing over $50,000. Box speakers are the hard way to design a speaker and Sonus Farger spent decades on perfecting their midrange cones and other engineering feats which when compared to Magnepan are what Jack Northrop called inventing rubber gloves to write with a leaky fountain pen.

Both my house and my budget are not big enough for anything bigger than the 0.7's, which I drive with 833-A single ended triodes. (See my system.)
