Interstage Monoblock 300B

Interstage Monoblock 300B

The Interstage amplifier is our highest and most extreme expression of Single Ended Amplification reserved only for the true connoisseur audiophile. The Interstage transformer design style is currently used on Audio Note's top of the line On Gaku 211 amplifiers.

The unique design style makes use of an interstage transformer on each channel - rather than having an additional tube driver stage, the interstage transformer takes over this task for ultimate authority! The Interstage Mono Block provides a level or realism and detail that you may not have experienced.

Recent enhancements to the blocks have taken them to a totally new level. We have a new Mains transformer - the T-195 dedicated to the Legend & Interstage MonoBlocks for both parallel and single Triode configurations. We have enhanced the Choke to anew CH-170 for 300ma capacity. The Interstage transformer is bifilar wound and sits on a very large Core for maximum bass response.

The mechanical design of the unit is second to none using all stainless steel metric hardware; countersunk screws and removable insert plates for a truly fun build experience. Power supply and driver circuitry is all hardwired and uses the latest Mundorf Mlytic 4-pole capacitor technology.
