I'd be VERY interested in hearing your opinion, as I have a RX-V1800 and RC-70s as well.
No problem. The XPA2's are supposed to ship to Emo the first week in March. I don't know how long it takes for them to get to Emo, given the probable hold up for a bit at customs. So I'm guessing we'll see them start shipping to customers in about 3-4 weeks.
