Zesto Andros II Phonostage

Sale price$5,200.00

Inspired by RCA’s vacuum tube circuit designs from the 1930s, the Andros has been engineered to bring you the clarity and depth of the original recording.

Features



• The Circuit is specifically designed to provide sufficient amplification to match your cartridge with the rest of your system.



• Each unit is hand built “Made in the USA”.



• 50 hour factory burn in on all circuits and vacuum tubes.



• A low Noise level of -80 dBv below maximum output allows the quietest passages of you music to be heard.



• The output circuit is designed to drive your cables and isolates the output from the influence of the next stage.



• RCA connectors are high quality, Gold plated, recessed with an isolated ground.



• Isolated ground RCA connectors plus the Ground On/Off switch will allow you to choose the best ground configuration.



• Recessed RCA connectors are durable and will hold up to the typical Audiophile who loves to change their configuration.



• All switches and knobs are easily accessible, nothing hidden inside to adjust.



• Two position MM switch 47K and 15K Ohms to accommodate more cartridges.



• 10 position MC load switch from 20 to 1000 Ohms and more in the sweet spot above 200.



• Accommodates both high and low MC output cartridges



• Elegantly designed 16 gauge steel enclosure to help isolate the electronic “chatter” from nearby equipment.



• On/Off power switch conveniently mounted on front side panel



• Easy to read large type on back panel
