HiFi Headphone Amplifier For Low Impedance High Sensitivity Headphone L.RA1 AC

HiFi Headphone Amplifier For Low Impedance High Sensitivity Headphone L.RA1 AC

Description:
When it is used with low-impedance, high sensitivity headphones for GRADO, it features a special sense of looseness. The circuit has no voltage gain, but only reduces its output impedance, and uses a large-impedance negative feedback circuit to counteract the back-EMF of low-impedance headphones. This design brings a very high SNR and control, and a delicate and relaxed hearing sense. When this amp is paired with our store's L1852DAC, L4490DAC, it will be very unique in the small compilation of vocals and chamber music, with air and soft high frequencies.

Features:
- Powered by AC power supply
