A discrete circuit is composed of electronic components which are disparate, individual devices, also called discrete components. These can be “passive” components, like resistors, capacitors and inductors, as well as “active” components, which in our case are transistors. The inverse of this would be an integrated circuit, which uses operational amplifiers (op-amps) in the signal chain. Countless hours of listening tests and years of experience have shown us that even the very best op-amps tend not to sound neutral, natural, dynamic or vivid. Standard phono pre-amplifiers with integrated circuits have tens or hundreds of components, but discrete designs will employ hundreds or thousands of components by comparison. This makes for an extended and more costly design process, but results in the pinnacle of phono sonic reproduction.
The Phono Box RS2 employs a true fully balanced design principle. Balanced transmissions consist of a hot and a cold (also called + and -) signal. Both the hot and cold signal chains effectively carry the same musical information. A true balanced amplifier can extract the musical information out of the hot and cold signals and remove all noise that is added as a result of external interferences. In a true, fully balanced amplifier, like the Phono Box RS2, the hot and cold sections of both the left and right channel are treated individually, which greatly increases the purity of signal resulting in inkier silences, enthralling dynamics, and a thrilling musical performance.
