Martin Logan Aeris i's with Rogue Cronus Magnum

What about using the 8-Ohm taps, is that not so good with regard to damaging the amp? I'm new to tubes, so forgive my ignorance. Thanks J!!

Mark at Rogue is a wealth on info and he assured me the 4 ohm taps are best practice, I was just curious. I've got a spare pair of small Brit monitors (Monitor Audio MA100's early 90's vintage, made in UK, not China) and hooked them up for grins. Sounded closed in and small by comparison, hooked the ML's back up and melted back into my chair with my ears thanking me every step of the way. My dad has all Audio Research gear and some more recent ML's and his seems to be a tad more analytica, while mine has the more typical tube sound.........vastly different rooms I feel is the major contributor to that though. I'm sold on tubes and ML's so far. Thanks for your input J!
