I've owned my 5-driver, 3-way, sealed box, dynamic driver speakers for 18 years. During that time I've owned or auditioned various RAM, Atmasphere, Cary, Joule Electra, VTL, ARC, Classe, Eagle, Boulder, PS Audio, RE Designs, and Threshold amps. For the past year and a half I've owned a pair of JC-1s and they provide the best overall musical presentation I've enjoyed with these speakers. If you are looking for power, driver control, and detailed musical but unfatiguing sound, the JC-1s are certainly worth an audition.
That said, without knowing anything about the efficiency or load of your speakers, it is difficult to suggest a recommendation. Plus I am not familiar with the current Spectrons.
