I emailed Jack a few weeks ago and asked about any "ready to ship" or imperfect products he had available. He replied saying he had a unit with a small ding that he would offer at a discount. It showed up 5 days later and I still can't locate the ding. If anyone is in a hurry, that might be an option. Based upon my experience thus far with Woo, I can't recommend them enough.
Looks like only new models cause delay. If Woo has parts on hand, amp will be delivered on time.
