Thanks, Newbee. Personally, I believe it'd be beneficial to Ty's potential customers if he published some impedance specs, but in the end that's his business. I'm only speaking as a consumer.
Though I realize they vary, I'm not that interested in delving into amplifier output impedances. No amp manufacturer publishes these specs, so it's info not readily available to buyers, which frankly makes Stereophile's reviews with bench tests so useful. It'd be a PITA to rent the required testing gear, and to learn to bench test amps that I buy or bring in to demo.
I'll trust my ears based on choosing gear that meets general guidelines. The Leben/Castle combo works. The Rogue/VR4 combo works. Overall, more amps work with higher impedance loudspeakers than with speakers that have low impedance dips.
For me, this is the "take away" from the thread you referenced in your most recent post.
