@unsound - thank you again. I hear you and am eager to hear about other options. I came to Benchmark via recommendations from high-end recording folks, tried it and like it. I can't explain how or why it outperforms its expectations.
I did connect a dot or two around the power spec idiosyncrasy. Due to its feed-forward error correction topology, the amp simply can't function beyond the limits of that brick wall. It can't be rated at 1% distortion because it can't produce power with 1% distortion.
