The "SB 10s" interface from fadel Art is really a unique product on the market. The goal of designing this absolutely outstanding symmetrizing interface was to realize a system, existing of one balanced stereo preamplifier and two identical units of an unbalanced stereo power amplifier. This unique concept results in a so far unknown quality of music reproduction which is an amazing improvement over the normal use of only one stereo amplifier.

For this interface we have developed a special correcting device in order to eliminate any phase shift and any impedance mismatching. A totally symmetrical topology for the positive and the negative conductors is used in order to eliminate also any intermodulation distortions.

As a result this concept is able offer an unbelievable and unsurpassed dynamic range in the music reproduction. The stereo amplifiers seem without any limit concerning their power handling capability. The transparency in music offered by this system can never be obtained with only one stereo amplifier. Also the amazing neutrality of the sound offered by this concept is based on the fact that the two power amplifiers are operating in a floating ground mode.
