Feliks Audio Elise MK II | OTL Headphone Amplifier and Preamp

Feliks Audio Improves Upon the Original OTL Amp in Stability and Power with the Elise MK II Incredibly detailed and dynamic presentation, virtually no background noise, typical "tube feel" Beautifully hand-crafted Beefier power supply and improved thermal management provide increased stability Internal shielding and transformer wiring bolstered to lower AC interference Revised cathode module improves sound quality Step into High-End with the Elise MKII The Elise is a high-end output transformer-less (OTL) headphone amplifier and preamp featuring PsVane 6SN7 and Russian 6N13S tubes. Amongst the Feliks line, the Elise falls in a sonic middle ground between euphonic coloration and detail retrieval. No sonic information is lost, and the signature is sonorously musical with a focused soundstage, poignant vocal presentation, and excellent extension. Whether you’re trying to tame slightly bright headphones without smearing over the resolution of your source, or you're seeking out something that will add a touch of warmth and vibrancy to your system, the Feliks Audio Elise is a highly capable amplifier for a wide range of headphones. Elise offers a dynamic sound stage and superb level of detail with the typical "tube feel". The amplifier is a fully proprietary design, built from high quality, carefully selected components, allowing it to deliver exceptional sound quality on a broad range of headphones, even of low-impedance (32Ω). Alternatively, Elise can be used as a pre-amp for both tube and solid-state amplifiers. What's New with the MKII The Mark II version of the Elise takes this hugely popular headphone amp and makes it even better. The power supply has been beefed up for more stable working parameters, and the internal shielding and transformer wiring has been improved for better AC mains interference protection. A revised cathode module improves sound on all output parameters. Improved thermal management and more efficient passive cooling results in 60% lower operating temperatures for improved longevity and output stability.
