Benchmark LA4 Line Amplifier

The LA4 is identical to the HPA4 except that it eliminates the headphone outputs. The LA4 is well-suited to customers who do not need the headphone amplifier.

The LA4 is a line-level preamplifier that is designed to sit between a reference-quality D/A converter and a reference-quality power amplifier. This is not an easy task. Most hi-fi preamplifiers introduce significant noise and distortion due to the necessity to provide volume control and input switching. To solve this problem, the LA4 is completely relay controlled and features analog amplifiers with vanishingly low distortion. It features relay gain control, relay input selection, and relay muting. The entire system incorporates the finest gold-contact relays available.

The LA4 is 100% analog. It is designed to be driven from external D/A converters and external line-level analog sources.
