Those look very nice, but they are quite inefficient at 85db/w, and low impedance. They seem to be begging for quality ss power. Depending on which tube amp Jake is using, perhaps one of the more sensitive offerings would be better? Although, for an office system, it may not matter, and the lack of loudness could be compensated by increased quality. (The Quarts I heard -years ago, not those in the link- imaged beautifully, and did the 'disappearing act' quite well. Squeaky clean studio monitor type sound, perhaps a little edgier than the M&K's I'm accustomed to, but clean and neutral.)
