Not exactly what you were asking for but I will share my experience. I have an ARC D400MKII(400watts/4ohms,& solid state) and an ARC VT200(200 watts/4ohms,& vacuum tube), On Magnepan 3.6's... The VT200 is much smoother,more focused, more dynamic, more detailed,heavier, more expensive, it requires expensive maintainace, and is a pretty good space heater too (16-6550's). From my experience it would lean to the VS110. Good Luck! Would you like to buy my D400MKII?
