Anyone had experience of Mk1 vs. Mk2 versions of Primare D30.2? From what I read, there are some major internal changes. Looking to get one 2nd hand but Mk2's are thin on the ground. There is a Mk1 on hififorsale.com at £700 but that sounds a bit rich to me. A Mk2 just sold on eBay for £720 but I completely missed the auction and didn't even get a bid in!
