Luxman Launched An Integrated Amp & Turntable
Japanese audio company Luxman launched the Luxman L-507Z integrated amp and PD-151 MkII turntable.
As part of the Luxman centenary celebrations, Luxman added the L-507Z Integrated Amp and the PD-151 MkII turntable to their collection. The L-507Z and the MkII turntable join the M-10X stereo power amplifier in the celebratory collection.
So what do we know about the new additions leading up to Luxman’s 2025 celebration? (Plot twist: Luxman’s centenary year is 2025, but it doesn’t hurt to start early)
The Luxman L-507Z Integrated Amplifier
The L-507Z is the debut model of Luxman’s new generation Z series of integrated amps. It features the company’s LIFES v1.0 amplification feedback engine. The Luxman Integrated Feedback Engine System is touted as much more than a mere evolution of the ODNF (Only Distortion Negative Feedback) circuitry. Instead, LIFES results from a systematic exploration of alternate designs, using dedicated software to simulate electronic performance across the entire circuit.
You can expect Luxman’s new LECUA1000 88-step electronically controlled attenuator integrated into the amplifier circuit. This results in reduced sound degradation over the full range of volume control. Meanwhile, instantaneous current supply and voltage stability are thanks to a custom-made EI-type power transformer and newly developed large-capacity filter capacitors (10,000µF x8).
Additionally, large, low resistance, parallel-configured speaker relays transmit the quoted 110W per channel into an 8ohm load or 210W per channel into 4ohm loads. Finally, the 300 damping factor has been attributed to direct wiring to the speaker terminals using Luxman’s proprietary OFC wire.
The amp sits on cast iron feet and features four sets of line-level RCA inputs, phono inputs for MC/ MM cartridges, and two pairs of balanced XLR inputs. In addition, fascia-mounted headphone jacks accommodate 4.4mm and 6.3mm connections. The Luxman L-507Z also offers two banks of speaker terminals (A and B).
The Luxman PD-151 MkII Turntable
The PD-151 MkII comes with Luxman’s S-shaped LTA-309 tonearm with knife-edge bearing tech developed by SAEC and an H4 bayonet headshell. The arm has an effective length of 222.5mm and an 18mm overhang. The arm base is machined aluminum, boasts a minimal contact area, and is mounted in a way that suppresses unwanted vibrations, we are told. As well as adjustments for anti-skating and stylus pressure, the LTA-309 can also be adjusted for arm height.
A DC brushless low-speed, high-torque motor is controlled by a Proportional Integral Differential (PID) feedback loop. Furthermore, for added precision, according to Luxman, the motor drives the outside flange of the 4kg aluminum platter through an “uncommonly wide belt” for stable 33.3, 45, and 78RPM playback via a speed selector on the front of the turntable where you will also find pitch adjustment, start/stop and power controls. Wow, and flutter is stated as 0.04% or less (WRMS).
The spindle supporting the platter is a highly rigid, 16mm diameter, hard stainless-steel shaft with bearings at the lower end. The bearing structure combines a thrust bearing lubricated with PEEK material and a brass radial bearing filled with organic molybdenum oil. You also get a turntable mat constructed from “special vibration-absorbing rubber material”.
Price Of The Luxman L-507Z Integrated Amp & PD-151 MkII Turntable
The L-507Z retails at £8,000 and the PD-151 MkII is set to arrive in September and carry a £5,000 RRP.
