Ah, valves. How we like their delicacy, sonic warmth and the way they light up. There are still valve amplifier manufacturers that work tirelessly to emulate that rich sound of the valve amplifier era.
PrimaLuna, Luxman and Cayin are designers and manufacturers of valve amplifiers that not only reproduce that classic valve sound but have made several improvements that enhance the sound quality and reliability of valves. Their designs run tubes at the minimum dissipation or power and give more slam and bandwidth through superior output transformer design.
