Hi Richard,
Glad to see your products and ideas are available for people to buy. I very much like the ideas behind the products and the simplicity of approach - something that in this day and age is rare.
Without going into subjective detail (yes or no will do), with high efficiency loudspeakers would a lower powered NVA amp be better than a higher powered NVA amp?
Also would it be worth trying in a Linn system with Kolektor/LK140?
