Know before you buy
The 120V rail technology provides significantly higher headroom compared to standard audio circuits. This results in a wider dynamic range, lower distortion, and a more natural, relaxed sound profile that helps reduce listening fatigue during long sessions.
Yes. The Director features a learning function that allows it to map volume commands from almost any infrared remote control, so you can integrate it into your existing setup without needing an extra controller.
Yes, the integrated DAC supports high-resolution audio, including PCM files up to 384 kHz and DSD files up to DSD128.
The Director uses a high-quality, motorized ALPS RK27 'Blue Velvet' potentiometer. This provides a precise, tactile analog volume control that maintains signal integrity better than digital attenuation.
The unit is highly versatile, featuring four digital inputs—USB, AES/EBU, coaxial, and optical—alongside two analog RCA inputs. For outputs, it provides both balanced XLR and unbalanced RCA connections to suit various amplifier configurations.
Absolutely. While it features a high-end DAC, the preamplifier section is fully capable of handling analog sources. When you select an analog input, the signal remains in the analog domain, benefiting from the 120V rail technology without any digital interference.
