Upstairs system: Horning Eufrodites singing wonderfully with the Whammerdyne 2a3. No crossover network in these speakers.
Downstairs: Magnepan 3.6r's are actively bi-amped via the Marchand XM44 using Coda S5.5 on the high channels, and Coda 15.5+ 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.
