Tekton is another brand I find interesting, and amazingly inexpensive…I'm tempted to order a custom veneered (zebra ebony…swamp recovered logwood...dagwood…tuck & roll) something or other someday as the high efficiency is tempting…then I could buy a single ended 3 watt tube amp. I second the in-home listening thing, although a tuck & roll finish might be hard to return…or dagwood, whatever that is (answer: Blondie's husband). Zu also makes an inexpensive AC cable that supposedly works.
