this site collects real adverts from Audiofools, for example this one is for a volume knob, a wooden knob, like a door handle .. yes, just a piece of wood. but .. that knob costs $485 !!!
Dynamics are better and overall naturalness is improved. Here is a test for all you Silver Rock owners. Try removing the bakelite knobs and listen. You will be shocked by this! The signature knobs will have an even greater effect…really amazing! The point here is the micro vibrations created by the volume pots and knobs find their way into the delicate signal path and cause degradation (Bad vibrations equal bad sound). With the signature knobs micro vibrations from the C37 concept of wood, bronze and the lacquer itself compensate for the volume pots and provide (Good Vibrations) our ear/brain combination like to hear…way better sound!!
