Output stage sampling expensive ON tube king MJE15034,35. Circuit uses the dynamic characteristics of the best no negative feedback architecture, Pure Class A output. So have a very low output impedance and frequency response was very wide, five times higher than the low end of the TPA6120 load capacity, headphone load range 8-600 Europe. Can even be pushed to small passive speakers. Voltage amplifier stage sampling LME49720 or OPA2604.
Similar products with unique protection circuit relay headphone amp (yellow picture element), so expensive headphones with peace of mind
Pure battery-powered, with the most expensive lithium-polymer battery, did not add any switching power boost circuit composed, long battery life 20 hours. Computers and other devices on the headphones and no high-frequency interference, the tone is more pure. Headphone jack is gold-plated pins, reducing the contact resistance. All rely on USB charging port is to enhance the power amp with low battery plus boost switching power supply board, the results sound color purity declined, reducing battery life, sound edgy.
Total for all aluminum chassis, perfect slim without water chestnut pipelined design, very delicate.
