    I bought these speakers earlier this year to pair nicely with a new NAD 3050LE. These are amazing speakers, delivering precisely the beautiful, refined sound I was looking for. I've paired them with a KEF 12b sub which integrates superbly with the help of the Dirac Live intrinsic to the NAD 3050LE. Overall, I can't recommend these speakers enough and I look forward to a lifetime of enjoyment from some very special kit.
