ditto on the atc sia2-150: 150 watts of class a power and what smooth, open music it renders. build quality is awesome, a real beast. as unfashionable as it is (in these pages at least), i have paired it with some atc scm-12 monitors and the sound is superb. (wayne's fully-modded squeezebox 2 sources this setup - can i plug wayne here?!). the flat earth audio people are wonderful to deal with and are the u.s. distributors, i think.
