Horning Eufrodites singing wonderfully with either the 300b or 45 tube amps.
Magnepan 3.6r's are actively bi-amped with the Marchand XM44 using Coda 15.5 on the high channels, and one of the Hypex Apollon NCx500 on the bass panels.
The 3.6r's internal crossover network (from midrange to ribbon tweeters) has been updated with Sonicaps and Solen aircore inductors using stock values, and completely rewired with Neotech solid core OCC wire direct soldered to all drivers and Cardas binding posts. Mye stands add rigiidity and Gaia II carpet spiked feet finish absorb vibrations and provide improvements in clarity.
What a wonderful system! Big Horning fan after hearing them at a dealer and in my home! Paired with a nice SET tube amp they really sing. Also, nice job on your room both acoustically and aesthetically. Love to hear it as the set up details and gear are sure to sound fantastic!
