With regards to the Plinius, I believe there is a review on the Magneplanar, the reviewer did use the Plinius amplifier, but not sure which model. So believe it might go well together.
The reason why I'm looking at the Myryad MXI2150 is because I'm can get a very good deal of about half the price for a demo unit.ÿBy the way, I'm in Australia. ÿ
As for the budget, maybe about GBP1000.ÿ
New powerfull amps for 1k are few and far between here's 2 that maybe a possibility.

Hope this helps if your willing to go second hand the options are greater bur remember these amps need to be auditioned with the speaker.
