Pure Class A analog preamplifier designed using medical and audiophile grade components.
The preamplifier section has two stages with very low noise FET transistors and paired manually to avoid the minimum signal variations. Includes ALPS motorized potentiometer with remote control and relays with very low contact resistance to avoid degrading the audio signal. The power supply uses high stability, very low noise voltage regulators and filtering with audiophile grade Nichicon capacitors.
The whole set has been placed in a CNC monoblock aluminum chassis, with several compartments for the different sections and avoid interferences between them. Thus, we have managed to reduce the figure of noise to the minimum level to obtain maximum pleasure in listening to our favorite music.
The preamplifier has a very minimalist format, with only the power switch, the input selector and the volume control, all finished in various colors, including chrome. All connectors are Furutech of very high quality.
The preamplifier is completely handcrafted, selecting the best components in the market and welding them manually on the printed circuit boards. Once the boards are finished, their parameters are adjusted in time intervals until the perfect result is achieved once the highest performance temperature has been reached.

We present a very high quality flexible MM / MC phono preamp with adjustable impedance and excellent technical performance. It is located in an aluminum chassis mechanized by CNC with different compartments to avoid interference between circuits. Discreet high class elegance.
The preamplifier was designed to listen at the reference level, so it is infallibly accurate and true to the input. Its purpose is to give it its music as intended by its artists and producers: nothing more and nothing less. The critical elements of a phonographic stage are: accurate RIAA equalization, low noise, low distortion and overload range.
The RIAA correction we have used is based on very low tolerance components. The resistances are metallic film and 0.1% tolerance. We have used Russian PIO capacitors (paper in oil) famous for their accuracy and consistency. The preamplifier section is responsible for a set of J-FET transistors that have been manually paired with a setting of 1%. The system accuracy is ± 0.25dB 20Hz-20kHZ, extending to 45kHz. This results in absolutely clear high frequencies without intermodulation or other anomalies that can distract us from our listening.
The signal-to-noise ratio in both MM (better than 82dB) and MC (better than 72dB) is outstanding and virtually inaudible in any volume setting. The distortion is extremely low, typically less than 0.01% in the entire audio band. The total gain is 70dB.

The ES9038PRO SABRE DAC is the flagship of the ESS PRO series. It sets a new benchmark for audio excellence with the highest dynamic range in the industry (DNR), up to 140dB, in a 32-bit, 8-channel DAC.
The ES9038PRO DAC also features ESS ‘32-bit HyperStreamDAC patented technology with total harmonic distortion plus noise 122dB (THD + N). The HyperStream architecture is responsible for both the excellent sound quality of the ES9038PRO and the extremely low THD + N.
It has a very low distortion, a very wide bandwidth and little noise. The technical performance of the DAC is on par with any other higher-priced DAC. The signal to noise ratio is -116dB (weighted ‘A’), the frequency response is flat across the bandwidth and the distortion is 0.0052% at 1kHz. These figures guarantee a completely neutral and accurate digital to analog conversion of any digital input. Includes USB input, DSD compatible (only under Windows).
As usual in the brand, the whole set has been put into a monobloc chassis of aluminum mechanized by CNC where the different sections have been compartmentalized to avoid interference between them. Thus, we have managed to reduce the noise figure to the minimum level to obtain maximum pleasure in listening to our favorite music.
