According to the company, the model uses best volume attenuation technology and enhances the audio signal with direct tube output (single Class-A tube stage amplification) or hybrid output. The streamer stage can run wireless, ethernet connections or via USB drive. Optional DAC module has a mode switch (bit-perfect or upsampled) and uses dedicated clock system. Headphones output based on tube-MOSFET Class-A hybrid scheme, and phonostage (optional) works in Class-A and suitable for MM and MC cartridges.
