The L-505Z is an integrated amplifier by Luxman that delivers 100 watts x 2 channels into 8 ohms and 150 watts x 2 channels into 4 ohms. It was released in 2024. It is a 2-channel design using a Class A/B output stage. Speakers connect via binding posts. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. It also has a phono input, so a turntable can connect straight to it. The Luxman L-505Z has an MSRP of $6,995.
There are 2 Luxman amplifiers in our database. Below you can see the main specs of these amps.
Luxman Integrated Amplifier Series
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Luxman L-505Z is rated at 100 watts RMS into 8-ohms. Luxman provides this wattage at a THD (Total Harmonic Distortion) of 0.009% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 100 watts into 8-ohms (20 Hz-100 kHz) at 0.009%
- 150 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 104dB Signal to Noise Ratio

We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Luxman L-505Z is rated at 100 watts into 8 ohms, which puts it in our 91 to 120 watts band. The next band up is 121 to 180 watts, which is worth about 1.5dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room. Plenty of systems are better served by the 61 to 90 watts band and better speakers.
When pairing the Luxman L-505Z with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
What size of room is the Luxman L-505Z Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Luxman L-505Z amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:
| Listening Environment |
Suitability |
| Near-field | Poor |
| Small Room | Average |
| Mid-size Room | Good |
| Large Room | Average |
| Very Large Room | Poor |
Inputs and Outputs
Besides the performance specs of the Luxman L-505Z, the next important feature set that you have to evaluate is the input and output selections that it offers.
Luxman L-505Z has total of 5 Analog inputs .

Bluetooth Connectivity
Luxman L-505Z doesn't have bluetooth connectivity feature. In order to stream your music via bluetooth, the easiest way is to connect an external bluetooth receiver to your Luxman L-505Z. Two bluetooth receivers that we recommend are the
iFi Zen Blue V2 and the
Audioengine B1.
Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:
Phono Input
Luxman L-505Z features two Phono Inputs which are compatible with
MM (Moving Magnet) type of phono cartridges, you can connect your turntable with MM cartridges directly to this amp without the need for a phono preamp. If you are using an MC cartridge on your turntable, you need to use a phono preamp that has MC phono stage such as the
Cambridge Duo or the
iFi ZEN Phono.
Balanced connections
Luxman L-505Z has a balanced XLR input. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more the connection is worth. Whether a balanced connection also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same power either way, so it is worth reading the maker's own wording rather than assuming.
Luxman L-505Z Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓100 watts per channel into 8 ohms, 150 into 4.
- ✓Signal-to-noise ratio of 104dB, so the amplifier itself should be inaudible between tracks.
- ✓Distortion is specified at 0.009%, an order of magnitude below what is generally held to be audible.
- ✓5 analogue inputs, enough for a full rack of sources.
- ✓Phono stage built in (MM and MC), for moving-magnet and moving-coil cartridges alike.
- ✓Balanced XLR inputs, worth having on a long cable run.
- ✓Headphone output.
- ✓Has tone controls.
- ✓Made in Japan.
- ✗Analogue inputs only - a TV, computer or CD transport needs an external DAC.
- ✗No Bluetooth and no network streaming - everything arrives over a cable.
