It's a lacquer that you paint over the tops of your ICs in your amp.
Quote:
filters unwanted (bad sounding) overtones from semiconductors like DA-converters, AD-converters, OP-Amps and Discrete Transistors
improves the sound quality of CD-players, DVD or SACD-players, Preamplifiers, Phono-Stages, Main- or Power-Amplifiers
transforms transistor sound into tube sound
transforms cold and harsh sound into warm emotional sound
attenuates odd, especially third overtones
easily applicated
performance can be monitored with FFT measurement equipment (AP)
all other specifications of treated components remain unchanged
no soldering or removing of components necessary
makes semiconductors sound natural
improves the sound quality of AD- and DA-conversions
