Benchmark manufactures DACs, preamplifiers and power amplifiers. This video explains the various models and recommends several different system configurations. It also explains the upgrade path if you wish to incrementally build the ultimate benchmark system.
If you are using a separate preamplifier with your Benchmark DAC, then this video is for you!
Benchmark DACs Can Be Used With or Without a Separate Preamplifier
Most Benchmark DACs include preamplifier functions such as a volume control and audio input selection. These DACs are designed to directly drive virtually any audio power amplifier without the need for a separate preamplifier.
Nevertheless, if you chose to add an external preamplifier, you will want to change some of the programable features in your Benchmark DAC.
