Hi, Justin (OP) and all,
Subject to... your system, ears, preferences, etc.
I have had great results with Odyssey (Kismet mono's in the Khartago cases).
I don't have Martin-logans but have run the Kismets through my various systems that include B&W, KEF. Gallo and Quad ESL speakers, variously and comparatively driven by Levinson monos, Peachtree and Pathos integrateds, Kenwood LO-5 MII monoblocks (total sleepers, still good to this day, also very fast, well damped, etc.).
The Odysseys are perfectly stable into low impedance loads, very fast (slew rate?), good control (damping without overcontrol), etc., = reliably great sound.
Another benefit of working with Klaus & Co. at Odyssey is that you can pick & choose / customize many aspects as well as upgrade later.
A good example of which is setting the bias (Class A vs A/B). From the website:
"All amplifiers: Custom bias for your system prior to purchase. The customer has to provide system information to check feasibility. Free of charge." Nice. Might make sense for your Martin logans.
It is a smaller family owned business and the ability to speak with the CEO/designer, customize your amps, etc. means that it can take a bit longer than walking into a dealer (support your local dealer, too!) and taking it home that day. Well worth the extra time, "patience is a virtue", at least sometimes.
Lots of great gear out there. Enjoy the hunt...
Ken
