Zero-feedback class A headphone amplifier with Mundorf capacitors and an RCA pre-out.
Linear II: the design
The Linear II has low-impedance copper traces, Mundorf capacitors in the power supply and low-resistance MKP types in the signal path. Two Neutrik headphone outputs in parallel, one RCA input and an RCA pre-out to use it as a preamplifier too.
Lehmannaudio's headphone amplifiers, made in Germany, are built for high-level headphone listening: zero-feedback circuits and selected parts in the signal path.
