Description
The HPA-23RM stands as our premier headphone amplifier, engineered for discerning listeners who demand reference-grade performance in both stationary and portable settings. This dual-output design integrates a voltage amplification stage derived from the AMP-23R’s advanced MOSFET architecture paired with a refined JET2 Bias circuit, alongside a sophisticated current output topology rooted in the HPA-21’s proven bipolar transistor foundation. The result is a compact, thermally efficient solution that delivers our signature reference-quality amplification without compromise. Modern power supply innovations enable extended listening sessions while maintaining the sonic integrity that defines Enleum’s amplifier lineage.
