Timely discussion. A pair of Cornwall IV will arrive this week. I bought them looking for an alternative sound (low watt tubes, high-eff horn-like speakers) to my standard high watt, medium-eff cones and domes system. I’ll be trying them with my stable of 3 watt 2A3 SET, 18 watt EL34 PP, and 36 watt EL 84 PP amps. All vinyl. Should be an adventure! Bought from MD, and I’ve already lined up return shipping by freight, so this is truly an experiment.
FWIW, I brought in Spatial X5 last month and returned them. Not enough flesh on the sound for me, and they needed more power than I expected to energize my largish room. I'm not sure the CW will provide adequate bottom, hence the exit strategy.
