The Max amplifier utilizes the largest electronics module circuit board we have ever produced. This gold and black Max module sports tiny chips that cost $15 bucks a piece (!), 0.1% metal film resistors and polyphenylenesulfide film capacitors that are silver-soldered to 2-ounce gold-coated copper traces arrayed over a black-solder masked, 4-layer circuit board. This jumbo-sized module circuit board must be mounted on edge for better heat dissipation. Everything in the Max is deep into Class "A" bias configuration. It uses four discrete solid-state Diamond Buffers as ouput amplifiers, and eight single-package Burr-Brown OPA627 (four per board) which are amongst the most musical, articulate, and expensive op-amps available on the market! The superbly regulated high-current power supply in the Max is a dual mono topology, so each channel has its own accurate and lightning-quick power supply. The sound is impossibly transparent and refined but still retains an ultra-lively organic warmth, supremely accurate detail resolution and a blistering musical punch we believe to be unmatched in the headphone amplifier world. The subtle nuances of the music will become a living, breathing performance in your head....Pure bliss indeed!

Beyond the highly-useful optional DAC inputs (see 'Options' below), the rear faceplate also sports two sets of RCA analog inputs along with a single pair of analog RCA outputs, as well as power on/off and AC ground-lift switches. The front faceplate remains clean and sleek with a only a minimum of distractions: two parallel 1/4" headphone outputs and independent switches for gain, crossfeed, and brightness settings plus a rear-output defeat switch for when listening solely to headphones (instead of self-powered desktop/computer speakers).
