Back in the day, my father's Brook 10-C3 (Class A to a pair of 2A3 tubes) drove our RCA LC-1A, 15" coaxial speaker to room filling volume. No one asked if they needed another loudspeaker or amp... you were too busy enjoying the MUSIC. I think you have to ask if you are enjoying your MUSIC or not.
Does my amp have enough juice to power my speakers?
Having just read a review in Stereophile of my Audio Physic Step Plus speakers (which I have to my utter dismay ,knocked over and dinged AAAgh!), the author states that his Shindo Haut-Briton Power amp (20wpc) couldn't drive the Step Plusses and states that nothing less than 35Wpc could drive them. My dilemma is that I have a Line Magnetic 216 IA rated at 22Wpc that sometimes sounds heavenly and on other days sounds eeh. Do I need an amp with more boost?
