The following is from the manufacturer’s website: DAC/PREThe advanced Pre Box DS2 Digital is an universal and very flexible pre-amplifier and D/A converter of highest class. The built in D/A converter AK4490, from high end manufacturer Asahi Kasai Microdevices, has five different digital filters which let you shape the sound to your preference. It offers full DSD256 support and upsampling of all input signals to 768kHz from USB, coaxial and optical inputs. This realizes high-resolution sound playback with a rich sound field and bass representation with less distortion. It features five digital inputs as well as analogue line level input and phono line in. The BT receiver supports aptX for best wireless sound conversion. That makes it suitable for any source available. One variable, one fixed analogue output and also one to connect the Pre Box DS2 Digital to your subwoofer are available. The samplerate converter (AK4137) features three different settings (sound modes). All that makes the Pre Box DS2 Digital the most versatile audiophile pre-amplifier D/A converter in its price range!

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. The top grade power amplifier module guarantees fully load-independent frequency response, low output impedance and very low noise floor. It meets our highest sonic standards in terms of spaciousness and fine dynamics and provides sufficient power for excellent reproduction in normal living rooms. As a sonic guideline for Pro-Ject amplifiers the homogeneous liquid sound of audiophile tube amplifiers are used as benchmark. A four layered PCB enables us to use shorter signal paths, which are also responsible for the improved sound compared to its predecessor. Amp Box DS2 will fill your home with the lush, energetic and smooth sound, usually found in much more expensive products. As additional upgrade you can use our Power Box DS2 Amp to improve the sound quality even further. Features: - Superior Class D modules - Impressive signal spectrum and lower distortion - High efficiency from mains to audio power - Low heat emission - Stereo level input (RCA) - Loop output (RCA) - Isolated speaker outputs - Trigger input & loop out - Elegant aluminium - metal sandwich casing Technical Specifications: - Power output: 2 x 100W/140W at 8ohm/4ohm (both channels driven) - Frequency response: 10Hz – 50kHz (0dB, -3dB) - Channel separation: >40dB at 20kHz - Noise floor: >90dB - THD: <0.1% at 90W - Gain: 31dB - Pre in: 2 pair RCA (bypass input-output) - Input sensitivity: 550mV (100W, 4ohms) - Input impedance: 10kohm - Speaker connectors: 4mm banana plugs - Trigger: 12V switching voltage - Trigger in and out: 2-pole coaxial 2.5mm jack - Outboard power supply: +/-48/2,5ADC, suitable for your countries mains supply - Power consumption: 2.5A DC, <1W in standby - Dimensions W x H x D: 206 x 68 x 194 mm (Alu) / 240 x 69 x 194 mm (Wood) - Weight: 1670 g (Alu) without power supply / 2130 g (Wood) without power supply LINEAR POWER SUPPLYBetter power supplies facilitate better sonic performance. Pro-Ject linear power supply Power Box DS2 Amp was developed to make this improvement available to owners of 48V RS & DS Series amplifiers (2 outputs for optional monoblocking). A linear power supply consists of a massive toroidal transformer with shielding between primary and secondary windings, which acts as an isolating transformer and prevents penetration of interference from mains from reaching the audio circuitry. The transformer has a much higher power reserve compared to the standard power adapter, very low output impedance with a large filtration capability. What you hear is improved soundstaging & imaging propelled by silent backgrounds, also making micro-detail more available to your ears. - Replaces original “switching” power supplies - Big toroidal transformer with copper shielding - Significant sound improvement with better dynamic and bass response, improved soundstage - Filtration capability 40.000 uF capacitors low ESR types - Very low output impedance Weight 3 kgDimensions 20.9 × 20.6 × 7.1 cm To avoid magnetic interference do not stack amplifier and Power Box DS2 Amp.

Excellent, nearly new, Pro-ject Pre-box DS2 preamplifier/DAC. This is the Digital version of the Pre-box DS2 and has a very nice DAC built in. Several connection options including MM/MC phono input.Comes with the remote. Amp and remote work well. Very nice sounding, and has adjustable gain to use with lower output sources. I almost decided to keep it (and still might), but I really dont need it. Just for general information, Pro-ject makes nice stuff (I also have an RPM 9 turntable) and they have exceptional customer service. I own a DS3 cd player that I had an issue with and they took care of it quickly and painlessly. They are great to communicate with. At any rate, nice preamp at a nice price. I have the box and papers. Comes with the Pro-ject power supply. Buyer pays shipping and payment is via Ebay on line. No international shipping except Canada
