- Single-ended, zero feedback circuit topology and demanding pure Class A operation and removing the need for a phase splitter.
- Fully symmetrical construction and offer a wide range of symmetrical (XLR) and asymmetrical (RCA) inputs and corresponding outputs.
- The pre-amplifier circuit boards are of symmetrical double-mono construction.
- The elaborate volume regulator is created by an R-2R network that has the same impedance at 128 possible, logarithmically tuned levels and guarantees an extremely good synchronism down to the lowest volumes.
- The new design uses low noise toroidal transformer in external supply.
- Build in DS audio EQ and MC/MM phono.
- Build in high-quality headphone amplifier.
- All-metal infra-red remote control handset.
- The components and materials employed are uniformly of top quality.
