George Counnas, founder and chief design engineer of Zesto Audio says, “I designed the Spirit so it would retain only the essential features of its predecessors, while still offering the Zesto Audio signature sound.”\u003c\/p\u003e\n\u003cp\u003eGeorge admits how challenging it is to design a high-quality product that sounds good at a low price point. The new full-size 17″ x 12″ enclosure design represents the new Spirit line of products in development at Zesto Audio. The Spirit is made with 16-gauge steel for better grounding to help isolate the electronic “chatter” from nearby equipment. \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe ESP Supply is so named because it anticipates the energy needs of the music. Zesto’s ESP Supply unlocks the true potential of the circuit, so it is at ease and doesn’t have to work as hard. It allows more music to flow through with more detail. It also creates a more dynamic presentation, the quiet passages are quieter, and louder passages have more punch.\u003c\/p\u003e\n\u003cp\u003eThe Andros Spirit uses 100% analog tube circuitry without any solid-state devices in the signal path. It uses a quad of 12AX7, which provides sufficient gain with minimal noise. There is a safety switch to discharge the high voltage before changing tubes.\u003c\/p\u003e\n\u003cp\u003eThe high-quality built-in MC step-up transformers are designed for better phase linearity which translates to better stereo imaging. It offers three of the most popular loading positions, 100, 250, 500, so you can dial in the best match for your cartridge. Users can adjust the MC load on the fly without clicks or pops. All MC loading is on the secondary of the MC step-up transformer. This allows all the delicate signal from the cartridge to pass through to the main circuits for the most musical detail.\u003c\/p\u003e\n\u003cp\u003eTo save money for moving magnet only users, the Andros Spirit is available in an MM-only version that is easily upgradeable to the MM\/MC version. \u003c\/p\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eIlluminated tubes for a more sensuous musical experience\u003c\/li\u003e\n\u003cli\u003eEach unit is hand-built in the USA using US and imported parts \u003c\/li\u003e\n\u003cli\u003e50-hour factory burn-in on all circuits and vacuum tubes\u003c\/li\u003e\n\u003cli\u003eDual mono circuit which creates better stereo separation\u003c\/li\u003e\n\u003cli\u003eTwo toroidal transformers: High voltage (300 V),  low voltage (12 V)\u003c\/li\u003e\n\u003cli\u003eRIAA curve is achieved using a passive filter\u003c\/li\u003e\n\u003cli\u003e1% metal film resistors throughout\u003c\/li\u003e\n\u003cli\u003ePolypropylene capacitors throughout the audio path\u003c\/li\u003e\n\u003cli\u003eAll switches and knobs are easily accessible, with nothing hidden inside to adjust\u003c\/li\u003e\n\u003cli\u003e16 gauge zinc plated steel enclosure\u003c\/li\u003e\n\u003cli\u003eTwo-year limited warranty, six months tube warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eMM Impedance:\u003c\/strong\u003e 47 kOhms\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMM Capacitance:\u003c\/strong\u003e 200 pf\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMC Impedance:\u003c\/strong\u003e 500, 250, 100 Ohm\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Impedance:\u003c\/strong\u003e 10K Ohm\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMax.
