Oz, my post meant to read "when driven into hard clipping, which is hard to do, considering the outstanding dynamic capabilities of the amp, it (signature) exhibits the same solid state glare that we all know and love (I am being facetious of course). This last statement was targeted at tube cognoscenti like you to illustrate the point that though it is indeed a solid state amp (as evidenced by the above caveat) unless forced beyond its considerable limits it sounds wonderful, and in fact exhibits some of the best qualities of tube amps. I'm like you, for about the last 25 years, my system consided of primarily tube amplification. Conrad Johnson PV-6 and more recently the Melos SHA-1 preamps, Michaelson and Austin TVA and Moscode amps. There will always be a place for tube amplification for me, in fact I'm tracking down the best tube integrated for an office system to use with Totem Arros for closed miked, more intimate works with the occasional orchestrated piece (any suggestions?) but the DK Mk III looks like it's going to be a permanent fixture in my living room.
