I don't know if I would refer to it as a plug, just pay additional shipping and handling......
I would love to hear the Q1 and Q3. I think the Q3 will sell very well, as people who would not ordinarily spend that kind of money, especially in this economic environment, who will stretch their budget to afford the Q3 as a sort of "final speaker" purchase. Too bad they are not an OTL friendly impedance, or I'd seriously consider them.
