Luxman L-505Z Integrated Amplifier

The L-505Z, along with the L-509Z and L-507Z, features Luxman's advanced "LIFES" amplification feedback engine, a cornerstone of Luxman's next-generation amplifier technology. LIFES, derived from Luxman's innovative ODNF feedback circuitry, offers superb static performance by not feeding the musical input signal back into the main amplifier, resulting in a natural sound reminiscent of a non-feedback system. The circuit has been completely redesigned, incorporating selected components and extensive listening tests to achieve superior performance and sound quality. LIFES Version 1.0 offers enhanced performance through a simplified and reconstructed circuit, reducing distortion by halving the number of parallel elements. The output stage utilises a parallel push-pull configuration with bipolar transistors, delivering robust Class AB power at 100W+100W (8Ω) and 150W+150W (4Ω).

Electronically controlled attenuator LECUA

The volume control is essential for the functionality and performance of an integrated amplifier, requiring precise signal processing. The L-505Z features LUXMAN’s proprietary LECUA (Luxman Electronically Controlled Attenuator), which has been compacted through a solid-state IC circuit design. LECUA offers exceptional level control with minimal audio quality variation and allows for smooth, detailed adjustments across 88 steps. Additionally, the LR balance adjustment utilises LECUA’s volume shift function, ensuring sound quality remains consistent throughout the volume range. The system maintains intuitive operation via the remote control, while the traditional rotary volume knob provides a satisfying tactile experience, blending convenience with refined operability.

Discrete buffer circuitry for preamp

Highly regulated power supply circuit

The power supply is crucial for an amplifier, ensuring both immediate current delivery and stable output voltages. The L-505Z features LUXMAN’s renowned 540VA EI-type transformer and four custom 10,000μF filter capacitors. This configuration delivers the necessary instantaneous energy for accurate musical reproduction and maintains consistent voltage under varying loads.

Large needle VU level meter and 7-segment LED

The L-505Z, akin to Luxman's premium models, features prominent needle-type VU meters with white LED backlighting for clear visibility and smooth signal response. A new 7-segment LED level display is positioned between the meters, enabling volume level monitoring from your listening position. Both the meter lighting and LED display can be controlled via the remote.

Headphone terminals with independent grounding

The L-505Z's advanced headphone playback capabilities are designed for the most discerning listening environments. It features both a standard φ6.3mm terminal and a new φ4.4mm terminal with independent ground wiring and separate unbalanced amplifiers, significantly enhancing left-to-right separation. When paired with compatible headphones and cables, this setup delivers superior, three-dimensional sound quality.

Versatile Inputs and Output options

The L-505Z features Luxman's proprietary tone controls, loudness adjustment, LR balance control, and a dedicated function for bi-amp setups or integration with AV amplifiers, all within a single unit. Its rear panel includes 18mm pitch RCA input/output terminals for high-quality cables with large connectors, and robust speaker terminals with an in-line layout that accommodate Y-lugs and banana plugs.

We endeavour to despatch same day for orders placed up to 1pm on available stock items (items with stock message "Usually dispatched within 24 hours"). Please remember to check with us first for a physical stock check if next day delivery is important to you. Any items with stock message "Usually dispatched within 72 hours" are items that we do not hold in stock but order in from the importer or manufacturer as soon as a customer order is received. Occasionally these may be delayed beyond 72 hours due to importer/manufacturer stock levels but we will inform you as soon as we can if this is the case.

UK Orders

We despatch the bulk of our UK mainland items on a 24 hour service – Free of Charge. Non Mainland locations - Isle of Man, Isle of Wight, the Scilly Isles, the Scottish highlands and Islands, the Channel Islands and Northern Ireland may take a day or so longer and are not Free of Charge. Smaller items are delivered using Royal Mail 24 or special delivery. Larger items are delivered using a courier service such as DPD or UPS.

International Orders

Due to the nature of our products and brand restrictions we are only able to send certain items internationally. Smaller items are delivered using Royal Mail Small Packets Airmail with International Tracked and/or Signed depending on value of item and availability of the service. Larger International shipments are sent by insured and tracked services using UPS. If there are any delays due to specific customs regulations, etc, you will be contacted by Hifisound or by the courier with a request for any further information required. Customs duties can apply for shipments to any countries outside of the UK depending on where the product you have bought is made. Customers are responsible for all taxes and duties incurred when the items enter their country.

Collect in Store or Home Install

At the request of the manufacturer some items cannot be supplied by mail order but you can click and buy them and then elect to collect them from our store or arrange a home install (if applicable). Applicable items clearly state that they are Collect in store or home install. Once ordered you will receive a message prompting you to contact us by phone or email to arrange for us to deliver and install or to reserve and collect from our store at your convenience, you will also be advised of the delivery time / stock availability as not all Home install / collect in store items are held in stock.
