BAL Integrated Power Amplifier

Design Philosophy

To design a practical, dependable, easy-to-use integrated loudspeaker amplifier that is beautifully crafted, sonically stunning, and enjoyable to use. We achieve this through a simple circuit and execute it in a carefully planned implementation.

Class-A, fully balanced, all-tube with in-house custom output transformers, zero feedback, 25 watts per channel. A dual mono integrated amplifier configuration that is uniquely equipped with a dual motorized volume control, allowing independent volume adjustment for left and right channels to dial in the perfect soundstage. 

The chassis is a one-piece construction, machined from a massive billet aluminum block. The finish is sandblasted and anodized in sophisticated black and gold trims. There are 3 analog inputs (two XLR and one WBT RCA) that are selectable via the front of the right dial. The output is via one set of WBT Nextgen speaker binding posts. The amplifier output impedance can be easily switched between a standard configuration of 8 Ohm or 4 Ohm via the front left dial. Standard features include a soft-start and faulty-tube detection / protection. The amplifier includes a matching volume remote control that is made out of a solid piece of anodized aluminum, accentuated with gold-finished buttons.
