Many of the stores I've visited are using the 8 ohm taps with Martin Logan's because a lot of people like the way they sound and I've been running my Ethos that way for a year now with no issues with my MC-601's. When one of the stores in Dallas had a Martin Logan rep in to demo the 15a's a few weeks back they used the 8ohm taps with the 601's for the demo. The 452 and 13a's should be awesome!
