H-INT
Hybrid Power Amplifier
The H-INT hybrid integrated amplifier consists of a preamplifier with a 12AU7 triode valve and the power section consists of a class D module providing 240W per channel. The H-INT has been hand crafted and encased in a beautifully shaped chassis made from a several parts of aluminium.
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, a volume control and a small display showing the volume control.
TECHNICAL INFORMATION
The input circuit is composed of a 12AU7 valve. Includes electronic 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.

PPM-1M
Phono Preamplifier MM-MC
The PPM-1M 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.

PPM-2L
Multi RIAA Phono Preamplifier
This phono preamplifier for historical curves allows for the selection of various equalization settings that predate the RIAA standard. Instead of using a single filter network, it incorporates multiple combinations of time constants. These include curves associated with labels and formats of the era—such as Columbia, Decca, and NAB, which were used prior to standardization—in addition to the standard RIAA curve.
TECHNICAL INFORMATION
From a technical standpoint, this historic preamp offers low noise, sufficient gain, and appropriate input impedance—but, above all, a precise equalization network. The various curves can be selected without introducing noticeable level changes or additional signal coloration.
This type of preamp is particularly useful for collectors of first editions, 78 rpm records, and LPs from the 1940s and early 1950s. Far more than a mere historical curiosity, restoring the original equalization allows for a much closer approximation of the recording medium’s intended sound.

PDAC-1M
Digital to Analog Converter
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.
The whole set has been put into a chassis of aluminum. 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)
