One of this design's innovations is its flexibility, which allows the user to upgrade and/or customize their system based on their changing audio needs. It also offers the advantage of a wide number of options aimed at avoiding outdated system configurations as user needs become more demanding.


The preamplifier section of the unit is based on two dual triodes (12AU7) per side that act as unity gain buffers coupling the source and the power amplifier. The circuit was born of the knowledge and experience acquired in developing the highly acclaimed Margules SF220 line stage. The power supply of the preamplifier is fully regulated. Good power regulation reduces the loss of signal integrity that occurs when the signal itself shifts the preamplifier's operating point.The filament supply is also regulated.


The topology of this discrete semiconductor power amplifier is laid out in such a way that all coupling is direct, avoiding interstage capacitors that, in most cases, result in higher distortion and inferior sound. The output stage is designed with a proprietary circuit bias. This optimizes the operating point of the semiconductors so as to avoid the typical overheating found in other Class A designs while at the same time avoiding the pitfalls of Class B distortion..
