Original preamp suspension system To reduce physical and sonic vibrations

Spotless A1 preamp suspension system follows the principle of sound isolation suspension. The top preamp part is a suspension layer to reduce the external vibrations. In the sound isolation suspension system, the preamp and space slight vibration and acoustic vibration isolation, so that the preamp work will not be affected by excess vibration brought about by standing waves, so that the sound’s clarity and accuracy are guaranteed.

 

Fully manual discrete components
Preamp & poweramp independent power supply solution

Spotless A1 preamp uses 6N8P 6P6P electronic tubes for a two-stage amplification and a feedback-free design. The power supply is in the form of tube parallel voltage regulation. Give full play to the feedback free form of the circuit sound effect with vivid and natural features. The power supply part uses the characteristic UI-type transformer. sound balance and warm, so that the sound is more infectious!

Wisdom makes the design steady . Design makes the sound graceful.

The preamp is powered by an independent power transformer, Philips fiLter capacitors, and three WY3P tubes to form a parallel voltage regulator circuit, which provides a stable power supply.
The amplification part uses a 6NSP and two 6P6P tubes, with selected components high current design discrete post-stage circuit. Sound performance is balanced, smooth, and dynamic with a broad field.
Spotless A1 is a mid-to-high-end stereo music listening tube amplifier. It’s designed for bookshelf speakers or 8”-12" relatively neutral speakers to strengthen the dynamic and thick sound bottom so that the music is more smooth, natural, and steady!

No Compromise
Adapt to Reality with Action

The development of the Spotless A1 amplifier was a long journey. Its bold and innovative appearance and complex structure have undergone numerous modifications to the design, process, painting, wiring comparison, and verification. The chassis shell uses a special steel plate precision laser-cutting process, including more than twenty kinds of screws, custom solid aluminum knobs, dual-channel level meter head, three groups of RCA input, and a set of Bluetooth input. No detail has been compromised in presenting the original Spotless family lineage.

APT-X LDAC Bluetooth 5.0 The CD-class sound quality of pure wireless sound

Spotless Al uses the latest Bluetooth 5.0 chip. Faster transmission speed, stronger signal, more stable connection, and lower power consumption. Bluetooth decoding support protocols: LDAC, APT-X, APTX-LL, APTX, SBC, AAC. Spotless’ Al applies Bluetooth receiver audio technology with APT-X, supports LDAC protocol, and supports up to 24-bit/96khz, allowing us to listen to music with better sound quality even with wireless devices. Enjoy the pure wireless sound of CD-quality audio anywhere, anytime. Bluetooth mode comes with CSR8675 + ESS9O18 featured decoder to further improve the sound quality and analysis for better noise suppression. Make the sound more transparent and smoother. When listening to music, you will feel the strong flavor of the vacuum tube analog.
