MM Phono Pre-amplifier.Good sound from sound technology  

This ultra low noise phono preamplifier benefits from outstanding circuit technology from Dr. Sykora, well-known from Phono Box DS+, in a slimmed version with almost same sound quality, but without display and relais switching at a more favourable price

When we started creating Phono Box S2, its successor, it had to have exactly that but improve on sound even further. Phono Box S2 features incredible micro-details, dynamics and precision with a soundstage usually found in much more expensive products. The new S2 style housing is made of an aluminium/metal sandwich construction and not only offers highest aesthetics but also out-standingly protects it from unwanted electromagnetic interferences and vibrations

Power Box S2 is a very efficient and flexible power filter for S2 line products. Its three outputs can power multiple units, such as power amplifiers, stereo amplifiers, streamers, turntables or DACs.  Clean energy contributes significantly to the sound quality and Power Box S2 can make a huge difference when comparing the system with and without it. The advanced technology in Power Box S2 avoids crossfeeding between the units and their power supplies. The DC filtration effect has direct impact on the sound quality. Additionally to the sound improvements Power Box S2 also offers its users a cleaner cable solution avoiding PSU and cable mess.

The Phono Box S2 Ultra is like no other phono preamplifier in its segment. The incredible success of our Phono Box Ultra 500, incited us to introduce this marvelously sounding phono preamp into our regular S2 line. The solid metal casing protects against interference and the internal design remains as spectacular as before.

With three line level inputs Stereo Box S2 offers the versatility to connect to many sources in your audio system. The world's smallest audiophile integrated amplifier offers enough power to drive even demanding speakers to their summit. T

Pre Box S2 Digital marks a new era for our S-series components. For the very first time we are using a dual mono configuration with the highest class D/A converters of ESS Sabre. Their flagship DAC-chip ensures highest class audio in a small and affordable package. This DAC is capable of high resolution audio up to 32bit/768kHz PCM and DSD512! Pre Box S2 Digital is also the very first of our devices to support hardware MQA unfolding.

Tube Box S2 is our very first product to feature a fully discreet circuit design without using any operational amplifiers (OpAmps). It also is the first product to come with replaceable tubes for tube rolling and sound-shaping. This gives the customer many options to pick from and alter the sound signature to his preference.

We at Pro-Ject Audio Systems strongly believe that a power supply is a very important part of the audio path and significantly contributes to the sonic quality of an audio product. In order to offer a maximum in sound quality and optimum isolation of the phono preamplifier from mains interferences, we designed the Power Box RS Phono with battery power output.

The heart of the Pre Box DS2 analogue is a pure single-ended Class-A output, an absolute High End solution. A new circuit design and a newly developed relais controled volume are responsible for the extremely low noise floor of Pre Box DS2 analogue.

A lot of people already have or plan to buy a very high quality turntable, driven by the fascination of the analogue sound. Many of them also want to record their vinyl in a simple, yet high-end way. The Phono Box DS2 USB is the perfect solution.

The heart of this audiophile amplifier is a Class D module which is highly efficient and energy saving. It delivers high output power, to drive demanding speakers and fill any room with pure sound, very low and frequency-independent THD to produce the cleanest sound possible

This ultra low noise and distortion preamplifier is made for the audio conniosseur and offers not only breathtaking performance but is capable to adapt to virtually any phono cartridge through variable impedance control. Impedance adjustment can be done while playback! Due to use of best parts, like SSM2019 from Analog Devices as input stages and Linear Technology LT1010 as high current buffer stage, Phono Box RS delivers ultra low levels of distortion and noise.

This precision tube phono preamplifier benefits from outstanding circuit technology from Dr. Sykora and uses ultimate components. Compatible with both MM and MC cartridges. It offers connection for two turntables plus two selectable line outputs and a continuously variable selection of input impedance for low output MC cartridges while playing a record!

Amp Box RS offers 3-dimensional sound-staging, perfect micro dynamics and ultimate resolution combined with high power output and 2 ohm capability and also is the perfect solution for Bi– or Tri-Amping applications.
