set vs otl, which is the most musical

Thanks everyone for the info. We've previously had amps that heated the entire upstairs of our apartment, as well as running up the electricity bill. I think if we had more space, and a quieter AC system, I'd jump at the chance to hear the OTL's. The only one I've heard represents merely a toe dip into the pool of OTL's. Jax2 came through last year with his Berning MicroZOTL, and we ran it through our Klipschorns. Understandably, it's 1 watt didn't lend much weight to the music, but oh my did the vocals sound delicious.

My Trios sounded not so good with an Atma-sphere M60. I think there is some impedence dips in the highs. The highs were rolled off. My Viva Auroras 845 are a perfect match. With my Silverline Sinfonias the M60 were very good. They are a flat 8 ohms. I still liked the Vivas better though. Way more goose bumps. I didn't find in my comparisons The M60 gives much of that. This is just my findings with my equipment. Others I'm sure might find different. OTLs do definatley need flat impedance. 8ohms or higher.

TVAD & others, bear with me on this one as I'm not as technically informed - I thought all OTL's used tubes in their output stage? The Moscode 401HR is a hybrid. Are the MOSFET's then somehow run without an output transformer? (I'm not sure I understand the design, but have heard and read nothing but big positives about the Moscode, so it must be doing something right!)

Can anyone clarify this a bit? Thanks.
