Loxjie A40 all in one amp 2024

[P1NBA11ER]

Right after setting it up, I had mine stop passing audio in one channel while using the phono input and then it died in both channels for the aux and BT inputs too, not long after. In trying to troubleshoot I switched to the headphone output and it worked fine. Switching back to the speaker out brought everything back to normal. Not sure if this was a “muting“ issue or not but it’s worked fine for about a week now.

No, but I think it's the peak protection. As I read this Elac has a max peak at 80Watt. If you need to have more "volume", you should get some other speaker, they are clearly not made for this.

I agree with your point.

I agree, which is why I'm not too concerned. Eventually they will be powering my Tannoy SRM-12Bs as soon as I can rebuild the crossovers.

Would be really awesome to have this unit measured by Amir or Erin.

Can somebody help with understanding the meaning of this filters and what they are use for?

• Fast and Low-latency filter: This filter is designed for quick response times without significantly altering the phase of the audio signal. It's ideal for users who want minimal delay between the source and the speakers, which can be crucial for gaming or watching videos where timing is important.
• Fast and Phase-compensated filter: Similar to the Fast and Low-latency filter, this one also aims for a quick response. However, it includes phase compensation to ensure that the sound from different frequencies arrives at your ears in sync, which can improve the clarity and focus of the audio.
• Slow and Low-latency filter: This filter provides a slower roll-off compared to the fast filters. It's designed to produce a more natural sound with low latency, making it suitable for listening to music where audio fidelity is more important than the speed of the response.
• Slow and Phase-compensated filter: This filter combines a slower roll-off with phase compensation. It's tailored for audiophiles who want a more natural and accurate sound reproduction, ensuring that the phase of the audio signal is preserved for a coherent soundstage.
• Non-oversampling filter: This filter bypasses the oversampling process, which can sometimes introduce artifacts into the audio. By avoiding oversampling, this filter aims to provide a more 'pure' and unaltered sound, which some users prefer for its authenticity. .

My amp arrived today. I have tried to read the manual but Loxjie site give me warning that is blacklisted. Do you have a manual?

Here it is...

Has amirm teste any MA5332MS based amp other than the SMSL A300

FX-AUDIO L07

SABAJ A20A

SMSL AO200 MKII

SMSL A300 according to this thread is inferior to the loxjie a40 (that one is tested but just shy of 110 watt in 4 ohm rated at 165 watt)

SMS AL200

Back to my PA-316 it sound really comfortable at medium to high levels (also partly to blame the speakers) and great full bodied bass

That is when you use chrome, firefox is fine

My first impression from Loxjie are mixed. Great functionality and power, but sound quality doesn't fees as an upgrade compared to my old Cambridge Audio a5. I am listening bookshelf speakers Dali Lektor 2.

How do you perform this type of comparison?

ps. thanks for the manual.

I recommend the Direct EQ (bypass) setting and experimenting with the different filters.

I returned the Loxjie A40 after I compared the sound to a Aiyima A07 MAX with a SMSL DL200 used as a preamp

To my mind/ears the Loxjie was ok, but the A07 and SMSL combo had and has an expanded sound stage, better definition and an overall richer sound..

[Mike_Trueman]

Does the SMSL AO300 sound the same as the Loxjie A40?

Has anyone else had this unit intermittently mute audio? I have mine connected to a pair of Elac BS-41 speakers and the audio intermittently cuts off at high volumes.
Usually at 50 or higher (Goes up to 60).

Yes, same here, somewhere around the same volume-level it (instantly) cuts out, recovers for a sec and cuts out again, repeats until volume is lowered. Wasn't really expecting this as I've never noticed this on the A30 this is replacing, but maybe I've never tried that one as loud..
Dropping the bass a couple of dB (using built-in EQ) and compensating with (active) sub-volume seems to help somewhat, so I guess it's just power-limited and best to not push it as far (to be fair, it's already properly loud below 50). Speakers are B&W 607 S2 bookshelfs (8 Ohm, 84dB sens., rated for 30-100W).

Mine A40 HDMI is not usable. Every 20-30seconds HDMI is mutes for a half a second. When i am incresing volume from tv is also muted.
Other digital input Optical have crackle every 10 seconds then input signal is shut. If its ON is quiet. There are no support from the manufacturer i have wrote already 4 messages.
Please when you are givind a feedback test well. I brought this amp just because here opinions were good and wanted digital inputs. It turned out to be complete garbage.

My A40 too has some sync problems on hdmi connection, so I connected it only optically to my tv, but noticed that until it has no audio input signal A40 has electrical noises that stop when there is an audio signal. So I turn on A40 as last device of the chain. Sorry for my bad English.

When my computer is connected to the DAC via optical cable, my E5XT also generates noise. However, when I unplug the optical cable, the noise stops. I believe it is due to the higher background noise of the optical interface compared to other interfaces.

Based on your description, it sounds more like a compatibility issue. It seems like your TV initially recognizes the A40, but then loses sound, which could indicate a disconnection. What model of TV are you using? Check the settings menu for any options related to HDMI (ARC).

 

[Combo86]

No issues with noise, (de-)syncing or mutes/disconnects here. Using it for my PC, so haven't tried connecting over HDMI, but optical and analog are working just fine. As long as I don't put it on eleven it will happily play all day.

Anyway, apart from that noise problem, I think A40 is a good compact dac\amp. For 260 euro now listening optically until 24\192khz ultra hd music is a real pleasure.
Coming from a 400€ Denon pma 600 amp the quality difference is great, even for my old ears.
