Spotless A Tube Preamplifier
Classic 12AU7 Vacuum Tubes: Three Russian 12AU7 vacuum tubes (two for input, one for output) create a low-output impedance, high-dynamic range amplification circuit for a quiet and dynamic performance.
Audiophile-Grade Components: Featuring audiophile-grade Vishay resistors and Philips, Suren, and Wima capacitors.
Wireless Bluetooth 5.1 with High-Resolution Codecs: Experience CD-quality wireless audio with the advanced 5.1 Bluetooth chip supporting LDAC, aptX-HD, aptX-LL, aptX, SBC, and AAC codecs. The QCC5125 Bluetooth chip combined with the ESS9018 DAC delivers exceptional audio quality and resolution.
Versatile Connectivity: One Bluetooth input and three RCA inputs allow connection to multiple audio sources, easily switched via the front panel knob.
Retro Design with Dual Meters: Spotless A features a retro-inspired design with a 2mm thick, hand-painted steel chassis, metal knobs, and custom-made VU meters.
