Authentic Transparency for Unrestricted Creativity

 

* Unsurpassed ambience retrieval

* Transformerless design with matched hi-speed discrete transistor octet has 23 dB input headroom: no attenuator “pads” needed

* Uncolored timbral accuracy at all dynamic levels

* Entirely balanced audio path with precision components maintains signal integrity: THD under 5 ppm (.0005%)

* Effortless, vividly realistic, musical performance

* Laser-trimmed FET-based output stage has 32 dB headroom: drives 1000 foot (300 m) cable runs with ease

* Standard 36-step gain controls (1.5 dB per step) are stereo matched to .08 dB

* Ultra-clean toroid power supply

* Gold audio connectors and switches

* Mogami Neglex OFC audio wiring

* Silver Teflon power wiring

* Welded 16 gauge steel rack chassis
