Zesto's philosophy is to focus only on the important components and add nothing that could compromise the signal path. The only active components are the vacuum tubes that create a warm musical sound.
As a longtime audio engineer and producer, George Counnas, designer and President of Zesto has worked with a lot of professional equipment. He has always preferred “true floating balanced” inputs and outputs because of their foolproof ability to isolate one piece of gear from the next. And that means lower noise for a strong, clean and quiet signal.
The Leto preamp will compliment any system: tube, solid state or digital. It will work with single-ended and balanced input source or power amplifier combinations. READ MORE....

The Chinook employs two triode sections of a 6922 for amplifying duties with highly accurate passive RIAA equalization networks. In the Chinook, the signal is then directly coupled to another 6922 dual triode serving as the output driver in a White Follower configuration. This output stage circuit is our favorite because of its super-low output impedance and beefy current-driving capabilities. It can drive long cable lengths and difficult loads. There are two internal settings for optimal gain: 45dB for Moving-Magnet cartridges and 60dB for Moving-Coil cartridges. The back panel contains DIP switches for adjusting the input resistive and capacitance loading values. 31 possible options between 26 and 800 Ohms plus 47k Ohms and 7 capacitive loading choices between 50 pF and 350 pF provide flexibility to match any cartridge.
The Steelhead has two Moving Coil inputs with selectable impedance loading from 25, 50, 100, 200 and 400 Ohms plus it has variable and selectable Moving Magnet input impedance options of 25, 50, 100, 200 Ohms and 47 kOhms. Very nifty is the selectable-dial-able-in-able-from-the-faceplate-able capacitive loading for all three of the MM & MC inputs 0 to 1100 picofarads in 10 picofarad steps. Very cool! Equalize baby! TEN picofard steps! Wow! Now you can really dial this in for perfect cartridge matching with ZERO penalty. None of this switching detracts from the sound quality or adds any extra anything to the signal path. The Steelhead uses 2 x 6922 plus 4 x 7044 or 5687 tubes, volume control for a direct connection to any amplifier, multiple inputs for up to 3 tonearms, selectable gain settings of 50, 55, 60 and 65dB plus a host of other features.

The Absolute Phono uses the Absolute Phono's innovative circuit design including the current amplification first gain stage. However in the Inside, this is incorporated within the phonostage's main body. Through careful fine tuning, Clearaudio have been able to deliver many of the improvements bought about by the Absolute Phono in a more conventional phonostage configuration. Both unbalanced RCA and balanced XLR inputs are provided for connection to any tonearm on the market. These feed the fully balanced current amplification first gain stage, avoiding any need to set cartridge loading and thereby ensuring a perfect synergistic match with any moving coil cartridge. This amplified signal then passes to the specially designed main RIAA phonostage, along a signal path free of the usual relays and coupling capacitors, which again enables a more clean, pure and accurate sound. The signal is then equalized and fed to the balanced XLR outputs. The result? The signal to noise ratio is significantly enhanced, almost matching the headshell-mounted Absolute Phono's ten decibel improvement. READ MORE....
The MC series moving coil step-up transformers are used to amplify the low level output signal from a moving coil cartridge bringing it to the appropriate level to drive a moving magnet phono preamp.
The MC series transformers are large size single C-core double coil transformers using a proprietary amorphous core material. Special winding techniques were developed in order to minimize inter-winding capacitances and maintain wide frequency response. They are optimized sonically to be as invisible as possible.
The transformers are shielded with mu-metal and are potted in 10mm thick soft iron nickel coated enclosures providing immunity to outside magnetic fields and a quiet and noise free performance.
MC5 may be used with cartridges from 0,8-1,2mv
MC10 may be used with cartridges from 0.4-0.6mv
MC16 may be used with cartridges from 0.3-0.4mv
MC20 may be used with cartridges from 0.2-0.3mv
The MC transformers were developed in conjunction with the VPS100 phono preamp but can be used with any MM phono stage. READ MORE....
The input stages of the Decade can also be found in top notch mixing consoles and high class microphone preamps of professional studio electronics.
