Meanwhile, back on the Monoprice amp... The "Black Friday"* price just kicked in. For US buyers this means you can now get the amp for $212 with free shipping. I should have waited a couple of days, but these are so often sold out, I did not think they'd come down in price and was afraid they might actually go up.
Too soon old, too late smart, as a buddy used to say...
*Big pre-Christmas shopping day the week of the US Thanksgiving holiday.
