SELECTED COMPONENTS

Power Supply

Linear power supply with toroidal transformer up to 300 W and schottky diodes with low forward voltage drop and a very fast switching action.

CRC Filter

CRC type filter with metal oxide resistors, Wima polyester capacitors and Panasonic electrolytic capacitors

PAM-2

Class A Analog Preamplifier

The PAM-2 has been hand crafted and encased in a beautifully shaped anti-vibration chassis made from a solid block of aluminium with individually milled compartments to avoid any interference.

 

We have managed to reduce the noise to the minimum level so you can get maximum pleasure when listening to your favourite music.

 

Its design has been studied to be as minimalist as possible, with just a power switch, an input selector and a volume control.

TECHNICAL INFORMATION

The input circuit is composed of manually matched JFET transistors. 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, LDO voltage regulators and filtering with high quality  capacitors.

PAM-3

Analog Preamplifier with Korg Nutube Valve

The PAM-3 preamplifier is based on a state-of-the-art Korg Nutube triode valve with very low power consumption and high performance.

It has been handcrafted on a chassis made from a solid block of aluminum with individual compartments.

 

Like the PAM-2, its design has been studied to be as minimalist as possible, with just a power switch, an input selector and a volume control.

TECHNICAL INFORMATION

The input circuitry that drives the Korg Nutube valve is made up of manually matched JFET transistors. Like the PAM-2, it features an ALPS motorized potentiometer with remote control, a power supply with high-stability LDO voltage regulators, and high-quality filtering capacitors.

PPM-1

Phono Preamplifier MM-MC

PPM-1 preamplifier

The PPM-1 preamp has been designed to listen at the reference level, so it’s infallibly accurate and true to the input.

 

Its purpose is to deliver the music as conceived by its artists and producers. Nothing else.

TECHNICAL INFORMATION

The most critical element of a phono preamp is the RIAA equalization.

 

For the RIAA correction we used metal film resistors, Russian PIO (paper in oil) capacitors, and a manually matched J-FET transistor array. This results in absolutely clear high frequencies without intermodulation or other anomalies that can distract you from the music.

 

The signal-to-noise ratio on both MM and MC is exceptional and distortion is extremely low, typically less than 0.01% across the entire audio band. The total gain is 70 dB.

MM
Input sensitivity: 3.0 mV
THD: 0.01%
Signal-to-noise ratio: >80 dB
Input overload margin: 15 dB

PDAC-1

Digital to Analog Converter

PDAC-1 preamplifier

The ESS9038PRO 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.

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.

The HyperStream architecture is responsible for both the excellent sound quality of the ES9038 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

TECHNICAL INFORMATION

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)

Specifications
