Ever since, Jeff continues to refine rechargeable battery DC power supplies and their application to reference grade amplifiers and preamplifiers, like the new twin chassis Criterion reference linestage, which sports in its control chassis, an incredibly sophisticated DC power supply, driven by industrial grade NiMH rechargeable batteries, which even exceeds the tremendous performance of its highly regulated switch mode AC power supply.
