About J. Sound Lab:

J. Sound Lab is a Subsidiary Company of MEG Tube Audio which based in Israel. We manufacture and make tube and valve amplifiers, headphone tube amplifiers and more. The company was founded by two brothers Edward and Michael Girshin, professionals with experience in tube audio & sound design for over 30 years.

The main principle of design of Tube Amplifier is the transmission of the emotional part of music and the diversification of the tone quality of musical instruments and vocal. The proper transmission of the sound by an amplifier is provided by correct circuit design, proper assemblage and meticulous selection of components.

One should not think that we are not paying much attention to the objective parameters of the developed amplifiers. Our amplifiers have low THD, high proportion of signal-to-noise and signal/hum, high damping factor and also wide audio frequency. All the parameters are measured in a real time.

Any designer of the audio hardware knows that the development of an amplifier takes a lot of time and mostly for selection of components-A/B tests. Listener process may take days and weeks! The founders of J. Sound Lab considers that A/B tests should give priority in each model of an Amplifiers the inimitable sounding, its own voice, to find out a genre advantages of a very model.
