Thanks again for everyones thoughts. Now the struggle is finding any integrated amps that will satisfy my friend (based on his loving the sound of the 518ia). It clearly needs to be something that won't overheat him, and the room, is available for $3-3500.00, used, and is somehow comparable to the sound of the Line Magnetics.
I've already discussed it with several audiophile friends that are familiar with the sound of the 518ia, and they too, are having difficulty coming up with something that meets all of the above. One initially suggested a Unison S6, which does sound like a real possibility, but I think that might also present a heating issue. Its a Class A amp, only moderately powered, but in the Stereophile review, John Marks notes that, " The S6 performed flawlessly, though it did throw off a lot of heat.". That surprises me since it uses EL34 tubes.
