The Emotiva PA-1 is an interesting Ice monoblock. It has one published review that I have seen. (135/270 watts rms at 8/4 ohms but only at 1 KHz.) Positive review ( https://hometheaterhifi.com/reviews/amplifier/power-amplifier/emotiva-pa-1-balanced-class-d-power-amplifier-review/). Balanced circuit, $300 per side. I am hopeful to hear it at AXPONA. If it's decent, it's inexpensive enough to get until the Gallium Nitride FET driver class D amps come down in price.
Just a thought.
