Atma-Sphere M60 monoblocks + ML ESL 11 = Inferior combo

Andy, Roger Modjeski designed his Music Reference RM-200 tube amp specifically to deal with low-impedance loudspeakers. When they occasionally become available on the used market, they fetch around $2,000 for the original version, a grand more for the Mk.2. A pair of KT-88 tubes are used to create 100 watts (per channel), into all impedances. The RM-200 is a VERY unusual tube amp.

In his original review in Stereophile, Michael Fremer placed the amp in the mag's Class A Tube category, and in a follow-up review found the Mk.2 iteration to be an even better amp. It has remained his "moderately"-priced reference tube amp for over a decade, and he recently declared the RM-200 MK.2 to be one of his most-cherished hi-fi possessions.

A Theoretica Applied Physics Bacch SP-adio. It is a crosstalk eleminating sound processor with a DAC doubling as a pre-amp. Works gr8 for me. But combining with a nice tube preamp is also something to consider!

…will read up on them! Thanks! 

@gdnrbob 

The pair I am borrowing are a pair of demos. Lets see at what price point they are for the moment.

…and you are right. They probably can handle any loads. Sounds terrific and have outgunned my beloved Bryston in most areas, Ive learned during the course of this day. 

100W per channel from a pair of KT-88s? Doesnt seem possible even for a quad of KT-88s.
