Luxman P-750u Review: Will appeal to any audiophile
The Luxman P-750u headphone amplifier is the flagship model in the Luxman catalog with uncompromising design and impeccable sound.
Unlike most similar devices, the amplifier is made in a metal case of a standard width for Hi-F components, which will allow it to perfectly fit into the existing set of audio equipment. At the same time, the low height of the unit ensures easy installation even in the case of limited free space in the rack. It can be noted that the weight of this model is 12.7 kg, which is comparable to this indicator of most integrated amplifiers, and indirectly indicates the solidity of its design.
The front panel of the Luxman P-750u amplifier, made of aluminum, contains balanced and unbalanced outputs for connecting headphones, as well as a full set of controls, including a very useful stereo balance control, rarely found in models of this class.
There is also a switch of inputs, of which the Luxman P-750u has three – two balanced and one unbalanced. Also, using a separate switch, you can adjust the gain of the device depending on the sensitivity of the connected headphones.
All switching in the amplifier is made on the basis of precision relays, which ensures accurate transmission of the audio signal.
The Luxman P-750u headphone amplifier has a true balanced circuit, while the amplifying part of the device is made on the principle of dual mono.
The device uses a patented negative link designed only to reduce distortion (ODNF) and does not degrade its phase-frequency characteristics..
The Luxman P-750u delivers increased power output of up to 8 watts per channel when balanced (16 ohm load impedance). The amplifier is designed to work with headphones with impedance up to 600 ohms, which makes it compatible with all models (except electrostats) on the market. The P-750u’s signature Luxman sound with a wide dynamic range and precise stage rendering will surely appeal to many audiophiles.
Most importantly, the Luxman P-750u sounds absolutely neutral and is able to squeeze the most out of any ears. We tried the familiar headphones of different price categories and in all cases with Luxman their potential was revealed to one hundred percent. Well, if you use models such as the Beyerdynamic T-1p or AKG Q701, you are guaranteed a rare immersion in the soundtrack in terms of the amount of information and reliability. Whether you are listening to a contemporary piece such as Elgar’s Enigma (performed by the Cincinnati Orchestra under Paavo Järvi) or archival recordings of Bach’s Goldberg Variations (Wanda Landowska), the atmosphere of the musical event engulfs you completely. However, the outstanding clarity also has a downside – if the instruments are recorded large and bright, which is what even classical music is sinning today, then the sound can become unnecessarily harsh and tiring. This is despite the fact that the bass register of the Luxman P-750u is unusually full-bodied, and the amplifier is not at all inclined to collect performers in the center of your head. On the other hand, if you want to experience such nuances, whether the original soundtrack on SACD was originally recorded in PCM or DSD, or to evaluate the quality of digitizing analog recordings, it is difficult to find anything better than the Luxman with modern reference-class headphones.
