This is a system that enables morenatural channel separation and wider sound stage by moving a part of the lowerfrequency range to the opposite channel.Listening to a regular headphones amplifier places you “in the middle of the orchestra”with certain instruments being heard strictly in the left ear while others only in the rightone. Depending on the type of music, this can cause discomfort and "listening fatigue".That`s why we decided to implement a user-switchable Cross-Feed function amongselected products. Our Cross-Feed function gives you a possibility to try a more natural,less clinical–“front facing orchestra” experience – like in real life!IN THE BOXMatched pair of driver tubes PsVane CV-181 Mk2 “Gold”Matched pair of power tubes 6N13S (NOS)AC cordUser ManualWarranty CardSPECIFICATIONSImpedance: 100 k ohmFrequency response: 7 Hz – 80 Khz +/- 3 dB (300 ohm)Power output: 280mWAmplification level: 20dBTHD: 0.4 % (300 ohm, 20 mW)Optimal headphones impedance: 32 – 600 ohm including planar magneticsHeadphones output: Jack 6.3mm
