Thank goodness I wasn't shooting with film: It took several frames to get a decent photo of the Da Vinci DAC ($31,000) from the California company Light Harmonic. But I didn't mind spending all that time trying, as the music was superbly tactile and compelling—thanks in no small part to amplification from KR Audio Electronics, represented at RMAF by the enduringly gracious Dr. Eunice Kron.
