Description
From my personal audio collection,Winner of the 2022 Phonostage Product of the Year award from The Absolute Sound.The Zesto Audio Andros Deluxe II Tube Phono-stage MC/MM Phono Preamplifier. This unit is in excellent like new condition. I bought it in 2021, its an open box item from an authorized Zesto dealer. It has performed wonderfully and well cared in our smoke free, children free and pet free home.The Zesto Audio Andros Deluxe II Phono-stage is a wonderful sounding piece of kit.It is totally quiet, transparent and just sweeps you into the music. and is a Stereophile Class-A rated component. Many great reviews online. Enabling MC or MM operation and dual arm capability.And it is ideal for tube rolling, which is quite a treat to find and enjoy different tube signatures!Comes with the original packaging and I will double boxed packaged for secure shipping.“The Andros Deluxe II Vacuum Tube Phono Stage from Zesto Audio is one of five, or maybe six, top phono stages I have ever auditioned. With its ultra-black background, excellent flexibility, and suave presentation, it is exactly the kind of phono stage that floats my boat. I am sure it is one of two or three tube phono stages that clearly compete for gain, definition, quietness, and neutrality, compared to the multi-box solid state beasts roaming the planet right now in the mega-buck price range. George Counnas is as clever as he is a genius. The Andros Deluxe, with its unique tube selection, clearly produces the passion contained in the musical performance itself. The Deluxe belongs at the top of your short shopping list now, and for years to come.”— BOB LEVI, POSITIVE FEEDBACK, 2018The Andros Deluxe II comes with Zestos new ESP power supply which is available as an upgrade for the Andros DeluxeWhat is the ESP (Energy Source Power) Supply?Zesto named it the ESP Supply because it anticipates the energy needs of the music. The new 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. The sound quality is an improvement throughout the frequency spectrum, so you have better clarity on the bass, midrange, and highs.Here are the top 8 improvements:The transformer changes from an IE to a Toroid design, which generates significantly less noise because it does a better job of concentrating the magnetic field.The high voltage increases by 17% from 250 V to 300 V which provides more headroomDynamic range is increased from 2 dBV to 11 dBV, so the quietest parts are quieter and the louder parts are louderThe ESP Supply is designed with bigger, fewer and heftier parts, which delivers more power with improved reliabilityThe rugged design of the ESP Supply makes it more resilient to power surges.Both the high and low voltage supplies provide more current, so it’s less restrictive to deliver more musicMaximum output level before clipping is increased up to 3 V RMS, depending on the unit to allow more punchIn the Phonostages, the noise level is 5 dBV quieter, which increases the black levels considerablyThe Andros Deluxe Phonostage is an exciting blend of Zesto’s award winning Phonostages, taking the very best attributes from both. It’s developed from the same footprint of the Andros 1.2 Phonostage and many of the internal features of the Andros Tèssera Phonostage, yet maintaining its own unique sonic personality.One of the unique features is an entirely new output circuit design that is based on the 12DW7 tube to drive the balanced output transformers. The main printed circuit board is dual-mono for better stereo separation. The input circuit incorporates the large, high-quality built-in MC step-up transformers that are used in the Tèssera. The are designed for better phase linearity. They are also large enough to accommodate all the extra windings and the Mu-metal shielding that reduces noise. This translates to better stereo imaging. The Andros Deluxe II is built with a passion for analog, designed with 100% tube circuitry and no solid state devices anywhere in the signal path.The tube complement is a pair of gold-pin, high-gain, low-noise 12AX7’s and a pair of high-current, low-noise 12DW7’s.FeaturesHigh-quality built-in MC step-up transformersIndependent ground switches affect both the MC-XLR and the MC-RCA inputs and reduce or eliminate hum by breaking ground loopsBalanced transformers reduce noise by providing a true differential signal and allowing the ground to float, making the noise level very lowThe MM-RCA connectors are always grounded to reduce noise from your cartridgeThe dedicated output transformers are driven by the 12DW7 output tubes providing an accurate balanced signal to your preampThe output RCA connectors have a floating ground and the XLR are grounded to reduce ground loopsThe tube complement is a pair of gold-pin, high-gain, low-noise 12AX7’s and a pair of gold-pin, high-current, low-noise 12DW7’sDual-mono circuit which creates better stereo separationA low noise level of -80 dBv below maximum output allows the quietest passages to be heardTen position MC load 1000, 800, 700, 600, 500, 400, 300, 200, 100, 50 ohmEasily adjustable MC “load on the fly” without clicks or popsThe gain switch applies to both MC and MM inputs, to better match your cartridges100% analog tube circuitry without any solid-state devices in the signal path, because tubes are inherently more musicalAll the RCA and XLR connectors are gold plated for better conductance and lower corrosionAll switches and knobs are easily accessible, nothing hidden inside to adjustEach unit is hand built “Made in the USA”50-hour factory burn-in on all circuits and vacuum tubesElegantly designed 16-gauge steel enclosure to help isolate the electronic “chatter” from nearby equipmentSpecificationsOutput impedance: 150 ohmMax output level: +9 VTube complement: 2 x gold pin JJ ECC83S/12AX7, 2 x JJ ECC832/12DW7MM impedance: 47 kOhmMM gain (dB): 45, 50MC impedances (ohm): 1000, 800, 700, 600, 500, 400, 300, 200, 100, 50MC gain (dB): 63, 68MC capacitance: 220 pfDimensions (WDH): 17 x 12 x 5Weight: 21 lbShipping Box Dimensions: 24 x 22 x 14Total weight: 30 lbsThis item comes with original box, tubes, cables and all accessories.And please take a look my other items.https://www.usaudiomart.com/userads.phpThanks!WayneWaynes Audio
