Balanced A1 Full Balanced Tube Line Preamplifier

After more than two years of research, testing, and development, we are proud to announce the arrival of our flagship preamplifier:
The Audio Experiences Balanced A1. A fully balanced tube preamp, the A1 is the latest design from the labs of world-renowned Mr. Chui Yat Sang. As a professional designer of premium audio products with over {{x}} years in development, Mr. Chui incorporates a hand-wired, point-to-point manufacturing philosophy into every high-end audio component that we offer. The Balanced A1 is by no means an exception.

Features

Innovative problem solving in the Balanced A1’s Class A, + wave auto-balance circuitry offers wonderfully realistic, dynamic, open-sounding music that will please the ears and stir the soul of even the most discerning listener. The gain stage of the main circuit is a fully balanced design, each channel using one 12AT7 and one 12AU7 vacuum tube to form zero negative feedback (0 NFB). The A1 line stage employs specialized tubes to project a clean, fresh soundstage while effectively preventing RF and vibration interference. The low impedance output stage is defining yet truthful to each note.

The Balanced A1’s application of a highly efficient solid-state regulator in the HVB+ power supply produces a sonic quality that is completely stable, lively, and rhythmically true to its source. At the heart is an extremely quiet power supply comprised of a fast, large current, R-core transformer. The shortest possible cable connections inside are the signature of the Mr. Chui ’s master craftsmanship.

Simply put, this preamp is perfect for people who love music. Only the ultimate components are included (Dale, Philips resistors, Wima caps) ensuring the most neutral sounding music and a truly extraordinary listening experience. No need to hesitate. Bring a home a sonic paradise with the Audio Experiences Balanced A1.
