Defunct brands-

Oops, forgot about the Phoenix Engineering Roadrunner Digital Turntable Tachometer and Eagle PSU Controller.

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.
