From Garage to Grammy - Pro-Ject Shapes the World Around the World

Pro-Ject Audio Systems emerged in 1991 from the ashes of the Austrian Tesla factory, founded by Heinz Lichtenegger with a mission to preserve analog music reproduction when CD threatened vinyl's extinction. Starting in a converted garage, Lichtenegger's passionate belief that analog deserved to survive drove Pro-Ject to become Europe's leading turntable manufacturer within a decade.

Today, Pro-Ject operates from their state-of-the-art facility in the Czech Republic, producing over 500,000 components annually. For over three decades, Pro-Ject has championed the philosophy that great sound shouldn't require a second mortgage.

Their Box Design series epitomizes this approach - stripping away unnecessary complexity to focus purely on sonic excellence. The company's commitment to in-house manufacturing and vertical integration allows them to maintain Austrian engineering standards while offering exceptional value. From their humble beginnings saving the turntable to becoming one of the world's largest hi-fi manufacturers, Pro-Ject continues to prove that passionate engineering and accessible pricing aren't mutually exclusive.

When Space Matters, Performance Doesn't Compromise

• Design Philosophy: The Amp Box DS2 represents Pro-Ject's commitment to the Box Design philosophy - delivering audiophile-grade performance in compact dimensions that fit modern living spaces without sacrificing sonic excellence
• Engineering Focus: Dual mono design topology with separate power supplies for each channel ensures complete channel separation and eliminates crosstalk for pristine stereo imaging
• Premium Components: Military-grade components throughout the signal path, including high-current MOSFETs and precision metal film resistors for minimal distortion and maximum reliability
• Versatility: Switchable inputs with loop outputs allow seamless integration with multiple sources while the 12V trigger system enables automated power management in sophisticated systems
• Thermal Management: Advanced aluminum chassis acts as massive heatsink, enabling continuous high-power operation without thermal compression or dynamic limiting

Not Your Typical Class D - The Analog Soul Inside

Traditional Class D amplifiers have earned skepticism from audiophiles for their clinical, sterile sound - often described as "digital" or "analytical" with harsh treble and compressed dynamics. Pro-Ject's implementation shatters these stereotypes entirely.

Their secret lies in obsessive engineering of the output filter stage and power supply. While budget Class D designs use switching frequencies that create audible artifacts and interference, Pro-Ject's ultra-high frequency operation pushes all switching noise far beyond human hearing. The result is the efficiency of Class D with none of the sonic penalties.

Pro-Ject specifically voiced the DS2 using tube amplifiers as their reference benchmark. The four-layer PCB with shortened signal paths preserves harmonic richness typically lost in Class D designs. The massive power reserves and instantaneous current delivery replicate the effortless dynamics of Class A amplification.

Most importantly, the DS2 achieves the three-dimensional soundstage and liquid midrange that audiophiles associate with tubes - that organic "breath of life" missing from typical switching amplifiers. This isn't Class D trying to sound like analog; this is Class D transcending its limitations to deliver pure musical truth.

The Verdict from the Audio Press

"The Amp Box DS2 punches well above its weight class, delivering the kind of refined, controlled power usually found in amplifiers costing twice as much. Its ability to maintain composure during complex orchestral passages while preserving micro-dynamics is remarkable." - What Hi-Fi?

"After the simple intimate ballads of Damien Rice, the more complex, intertwining choruses of 'Spem In Alium' are certainly a step up. The vocal warmth is repeated 40-fold, but there's precision, too, in the DS2's handling as each distinct voice takes its place in the mounting chorus, creating a towering sense of space worthy of the loftiest cathedrals." - Audio Advisor Review

What Sets the Amp Box DS2 Apart

The genius of the Amp Box DS2 lies in Pro-Ject's refusal to compromise. While competitors chase flashy features and unnecessary complexity, Pro-Ject invested every dollar into the fundamentals that matter: clean power delivery, vanishingly low distortion, and bulletproof reliability.

The dual mono architecture typically reserved for five-figure amplifiers ensures each channel operates independently, creating a three-dimensional soundstage with pinpoint imaging. The oversized power supply provides instantaneous current delivery for explosive dynamics, while the minimalist signal path preserves every nuance of your music.

This is amplification reduced to its essence - nothing added, nothing taken away, just your music presented with startling clarity and emotional impact. Pro-Ject benchmarked the homogeneous liquid sound of audiophile tube amplifiers, achieving that coveted warmth and dimensionality without tubes' maintenance or heat.

Ideal System Matching

Perfect for: High-efficiency speakers (90dB+), bookshelf monitors, near-field listening setups, desktop audio systems, secondary systems, apartment-friendly setups requiring serious performance without bulk. The high-current design handles difficult loads with ease while the compact footprint fits anywhere.

Demo Guarantee: This professionally maintained demo unit has been operated for under 20 hours in a controlled showroom environment, then carefully repacked with all original materials. Fully tested to meet factory specifications with Pro-Ject's complete 2-year manufacturer's warranty. An exceptional opportunity to own reference-quality amplification with minimal break-in time at significant savings.
