What is the best solid state amplifier you have ever heard?

1) EKSC Eagle 11 Prime Monoblocks-the best amplifier from Electron Kinetics-John Iverson and later updated by Russell Sherwood.  Difficult to come by as their owners never seem to give them up and not expensive.
2) A Pair of BEL (Brown Electronic Labs) 1001 Mk. V's in mono mode.   As a stereo amplifier it is very good but as monoblocks they are sensational.  My brother has a pair.  Richard Brown departed way to soon.
3) Bedini 25/25

One of the best I have ever used in 13 years of reviewing: 

EXOGAL Ion PowerDAC with HyperDrive (must be paired with EXOGAL Comet DAC). EXOGAL has made the PowerDAC a triumph. I think we're looking at the next generation of amplification here. 

Luxman 900u monos

The Exposure IV by John Farlowe ticked every box. Rich, fast, beautiful sound. Simple (but not simplistic) circuit with mosfet outputs and two superb, hand-wound transformers.

Burmester 878 --- hands down  !
