Balanced A2

Balanced A2 Full Balanced Tube Line Preamplifier

The BALANCED A2 is Audio Experience level 3 full balanced line preamp with Remote Control . it use NEW 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 and ONE 5687WB vacuum tube to form zero negative feedback (0 NFB). The A2 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 A2’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.
