Having lived with no fewer than two sets of Orions over nearly three years, I can attest that the thoudsnds of dollars one would spend on exotic amplifiers can be better spent in different areas (i.e. software).SL states this on his website:
"Much has been written about the sound of amplifiers in the Hi-Fi Press. Amplifiers can sound different due to non-linear distortion which generates new spectral components. The typical total harmonic distortion specification is merely a guide post and not a complete measure of amplifier distortion. THD should be below 0.1%, as a starting point, for amplifiers not to sound different from each other. More important is the distortion at low output power levels, below 2 W, where an amplifier spends most of its time during music reproduction, unless it is for Hard Rock. The crossover distortion of Class A/B amplifiers is impulsive in nature. It is very broadband and easily overlooked in the noise floor of the amplifier output spectrum. It registers low in a THD measurement, but the spectral components add in the time domain. They are responsible for much of the "solid-state sound". Class A amplifiers do not suffer from this inherent problem, but a well designed Class A/B can match their performance in practice. Amplifiers can also sound different when their relatively high output impedance, or low damping factor, interacts with the combined loudspeaker and speaker cable load impedance to cause a frequency dependent drive signal at the speaker terminals. This is very much an issue with tube power amplifiers and passive crossover networks. The ORION drivers present a simple load to their amplifiers, which are essentially driving the voice coils directly. No inductors or capacitors are in the signal path. Even tube amplifiers could drive the tweeter and midrange, but the woofer presents too difficult a load to their transformer output."
If SL recommends a specific amp to use with his speakers, it goes without saying that it wasn't by accident. Also, if the amp was a poor performer or inadequate in some way to power his speakers he simply would not recommend it.
So much for being an arm-chair critic.
