I agree with the analysis of Aisip above. I own both the Plinius SA-250Mk IV and GamuT D200 -using the Plinius on the woofers and the GamuT on the towers of the Nearfield Acoustics Pipedreams Loudspeakers. One additional comment- the soundstaging of the GamuT amp is without peer, Tube or SS, in my experience.
