Balanced P1-M   Full Balanced Tube Phono Preamplifier 


After more than two years of research, testing, and development, we are proud to announce the arrival of our flagship phono preamplifier: 
The Audio Experiences Balanced P1-M. A fully balanced tube phono preamp, the P1-M 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 P1 is by no means an exception.

 

Features

The Balanced P1-M has 45dB gain that is design for the use of  MM cartridge. The input impedance is 47K ohm. It can good work with over 6mV~ 2mV output MM cartridge.

Innovative problem solving in the Balanced P1-M’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 two 12AT7 vacuum tube to form zero negative feedback (0 NFB). The P1 phono 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 P1’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 phono 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 P1.
