I run Merlin TSM-Mmi with a Stingray II, which is basically the integrated amp version of the Mahis. Along with a small Von Shweikert sub, this combo fills a large room with great sound. The Stingray's 40 watts in ultralinear mode are more than enough, while its 20 watts in triode are not quite enough in my room. The Merlins are a tube-friendly 6-ohm load and the Manley amps are optimized for 5 ohms, so the match is good in that regard.
