Everyone wants the advantages of AC power line isolation offered by battery operation. The 20\/20 is for the person who wants those advantages, but does not want to mess with batteries. The 20\/20 comes as close as possible to offering an equivalence of battery isolation from AC line power. Second. Two-Mono (definition: bumping it up from dual-mono) construction. The 20\/20 is literally two identical mono phono preamplifiers. Each channel is on its own circuit board, has its own shielded compartment, power indicator, its own AC power supply and its own power cord.

Our proprietary, extruded FEP cables, with their thin, flat profile don't just look different - their deceptive simplicity is a uniquely elegant answer to the conflicting requirements for low resistance, capacitance and inductance that limit the performance of more conventional cable configurations. Now, the Red Dawn LS takes the benefits even further. By reducing dielectric effects still further as well as optimizing the physical spacing of the 20 heavy-gauge 12 AWG silver-plated OFC solid-core conductors we have produced a cable capable of phenomenal phase accuracy and detail, speed and dynamic range. From the quietest, most delicate note to the power of a thundering orchestral crescendo or driving rock track, the Red Dawn LS spans the range with effortless grace and deft control, allowing music to seduce when it wants to, or be savage when it must. Sitting at the top of the Leif Series, Red Dawn LS bears comparison with competing cables irrespective of price.
