Headphone Amplifier P-750u
New flagship model headphone amplifier featuring ODNF4.0, LECUA, 4-pin XLR & 3-pin XLR outputs
With a new stylish look, the P-750u, upgraded in every way, will be released this autumn.This unit features the latest version of LUXMAN’s original high sound quality amplification feedback circuit ODNF 4.0, eliminatingdistortion on all four channels.Unrestrictedexpression, extended range and energetic, yetnatural dynamic feeling are addedto the high tonal quality of the preceding model P-700u.For the unbalanced outputs, the output current capacity is doubled by pairing the four amplifier channel circuits into left and right and driving them in parallel. The balancedoutput has aBTL connection for high-end headphones and has many benefits such as greatly enhanced L/R separation performance. The P-750u has a 4-pin XLR balancedconnection, which is becoming standard for high-end headphones. The chassis feet are made of cast iron to block unnecessary external vibration. LUXMAN’s electrically controlled ultimate attenuator, LECUA, enables smooth adjustment of the volume control with minimal deterioration in sound quality. There is also a sensitivity switch, with which you can choose from 3 modes, depending on the headphone’s impedance and efficiency, L/R balance control and an on/off selector for through output. The P-750u is highly adaptable and you can further expand your direct listening environment.
