Defunct brands-

The RoadRunner and Condor motor controller are still in production,  Sota is manufacturing them under the permission of Phoenix. 

Just received their Quasar equipped with RoadRunner.  

Dahlquist-there were two versions of he company. I owned speakers from both.

Soliloquy Loudspeaker Company-5.3i speaker  was highly regarded

Meadowlark Audio-sold "transmission line" speakers. Swifts and Kestrels were considered top of line speakers, when the company folded in 2005.

@bdp24 : I too have an Electron Kinectics Eagle 2A amp. 

EmpireEars IEMs. Recently went under. IMHO, no loss at all.
