I'm sure the Mastersound 845s would sound wonderful. We heard the Ktema's with the Air Tight ATM-2211 which has about the same power as the Mastersound 845s and while it worked the ATM-2211 just didn't have the power to bring the Ktema's to life, at about 32W, as it's bigger brother the ATM-3211 which outputs 120W. Depending on how loud you listen and how big a room there are a lot of choices.
