Lehmann Audio Rhinelander Headphone Amp
Headphone amp, reconfigurable to single-source pre-amp! Different types of headphones make very different demands on headphone outputs as regards current and voltage. If you have ever connected your high-class headphones to a CD player or an integrated amplifier, you are aware of this problem. The Rhinelander is a very ambitious high end headphone amplifier for a beginner’s budget which can fulfill even very high aspirations. Its sonic kinship with Lehmann Audio’s top-of-the-range model, the Linear, is unmistakable. The powerful, discrete solid-state output stage in the low-distortion Class A operating mode with no global negative feedback also gives the Rhinelander a very transparent sound and has enough power reserves for the vast majority of today’s headphone sets. The gain of the Rhinelander may be adjusted via jumper for the different types of headphones. Selected top-grade components and a sophisticated circuit design guarantee an outstanding listening pleasure. Even in this device, Lehmann Audio uses dual-sided circuit board for an optimal layout and a genuine, studio-proven Neutrik headphone output socket. The potentiometers are hand-picked for excellent channel balance to maintain the localisation as it is on the recording. Its low-loss MKP capacitors in the audio path for a perfect transient response and quiet power supply with extra long-life capacitors are uncommon in a unit in this price range. Additionally the Rhinelander also features two inputs plus an input selector that uses a high-quality relay. If the second input is not needed, in can be reconfigured via jumper, turning the second socket pair into an output. Thus, the Rhinelander can also double as a high-end single source preamp, similar to the Linear.
