High-end and minimalist. Build quality: The materials and feel are excellent! I opened and tried it as soon as I received it! Thank you very much! Just tested it for a bit - the experience is great! The sound quality is relaxed, spacious, and has substance! For now, I've only experienced it with Bluetooth; I'll come back with a more in-depth review after trying it with vinyl and CDs!

ORIGINAL FRONT-END SUSPENSION SYSTEM

The Spotless A1 employs a patented suspension damping system to isolate its preamplifier stage from external vibrations, ensuring pristine sonic clarity and accuracy.

This innovative design minimizes interference and prevents the formation of standing waves, even under the most demanding conditions.

REFINED POWER & AMPLIFICATION

A dedicated transformer, Philips filter capacitors, and a trio of WY3P vacuum tubes in a parallel voltage regulation circuit provide a clean, stable power supply for the preamplifier stage.

The amplification stage utilizes a 6N8P and two 6P6P audio-specific vacuum tubes, coupled with a meticulously designed high-current discrete output stage. The result is a balanced, smooth sound with exceptional dynamics and a wide soundstage, ideal for mid-to-high-end stereo systems and bookshelf or large, neutral speakers.

This refined design delivers a rich, engaging listening experience, allowing the music to flow naturally and effortlessly.

PREMIUM COMPONENTS \ NICHICON & KEMET CAPACITORS

The Spotless A1 utilizes premium Nichicon and KEMET capacitors for superior audio performance.

Nichicon KG series capacitors are renowned for their transparent clarity, clean bass response, and excellent detail retrieval. KEMET gold electrolytic capacitors provide high voltage tolerance, large capacitance, and long-term stability, ensuring consistent performance even under demanding conditions.

These high-quality components are frequently found in top-tier audio equipment and contribute significantly to the A1's exceptional sound quality.

WIRELESS FIDELITY \ HIGH-RESOLUTION BLUETOOTH AUDIO

Spotless A1 delivers exceptional wireless audio performance thanks to advanced Bluetooth 5.1 technology with support for high-resolution codecs, including LDAC and aptX HD.

The QCC5125 Bluetooth chip, combined with a custom-tuned ESS9018 DAC, ensures pristine CD-quality sound with sampling rates up to 24bit/96kHz.

Enjoy a truly uncompromised wireless listening experience with stable connectivity and stunning fidelity.

A LEGACY OF WARMTH IN SOUND

The Spotless Al's precision engineering enhances the pure visual and auditory enjoyment of music. Its elegant, retro-inspired design features a pair of newly upgraded VU meters, its softly glowing needle dancing in time with the music. This captivating visual detail, especially striking under warm lighting, adds a touch of vintage charm. Spotless seamlessly blends classic industrial design and meticulous craftsmanship, evoking a nostalgic warmth while delivering a rich, nuanced sound.

BUILT TO LAST \ THE SPOTLESS A1'S ROBUST DESIGN

The Spotless A1's development was a journey of relentless refinement. From its bold, innovative design and complex internal structure to the meticulously chosen components, every detail was painstakingly considered. The precision laser-cut steel chassis, custom solid aluminum knobs, dual-channel level meters, and multiple input options reflect this unwavering commitment to quality.
