Loxjie A40 all in one amp 2024

Because it's a first use. Electrolytic capacitors need to form.

Do you have anything proving that?
I never heard about it before.

Because it's a first use. Electrolytic capacitors need to form.

... a process that takes seconds or minutes at best. And I bet the devices were tested before they left the factory. So, unless it was in stock for multiple months, all the forming was already done at the factory.

And the capacitors where also probably tested before beeing sold...

The vast majority of infant mortality failures are due to electrolytic capacitors. Some don't completely fail but change value, etc. In the analog world we would put a Variac on gear and slowly bring its voltage up for 1/2 hour to form their capacitors. You can't do that with digital, yet the caps still need to form.

No there is no need for that. Or I completely missed something during my years at school learning electronics, numeric and analog.

Probably. The fact that this isn't done anymore doesn't mean that caps don't benefit from it, does it?

You are right, but As you pretend that is has some benefits on the working of an amp and that you can hear when a cap is formed or not: do you have any scientific publication to share on the subject? Some measurement of before and after forming the caps please?

Does A40 provide this functionality:
- reads and plays audio files from USB keys/ USB memory
- works good from PC - USB connection
- have mobile app to operate/ mabage A40

?

Thanks.

 

[Tweeter2016]

I think the A40 is a bargain at twice the price.

But overall is it as good as SABAJ A30A?

 

[treehugga]

The Sabaj sounded to me like older generation class D - drier and leaner, but it did have a more holographic soundstage than the Loxjie.

no

yes (depending on what you mean by "good". I don't have experience with this, but I own the D40 pro which I have connected to a Raspberry-PI, this works flawlessly)

- have mobile app to operate/ mabage A40

no (there is no network connection)

How this can change because of the amplifier? Isn't it depending of the speaker, where and how there are place in the room from the listener?

Can somebody give a list of IR remote commands ? What a shame it is'nt radio.
Specially, how can we adjust custom EQ mode ?

Also, does NJW1194 volume control keep last level in memory for each entry ?

 

[dpuopolo]

I've had this unit several weeks now and it's great. It's my living room system, hooked to a WiiM pro coaxially and my 5O" TV optically. I'm running it into a pair of Elac BS-41 speakers and a Monoprice 12" amplified sub. Crossing over at 50 Hz. It plays loud and sounds incredible. The stereo imaging is amazing. Almost as good as my 3e mono cards.
It's well worth the $216.00 I paid for it at AliExpress.

According to the circuit design of their previous product A30, it is indeed the njw1194 that is used as the final stage for all inputs.

I ordered one from hifi-express on March 25th and it arrived today, no drama, total of $225.00. I couldn't find a way to get AlliExpress to ship to California.
Initial listening impressions are it sounds fantastic using optical in from a WiiM streamer to my Ascend Acoustics towers.

Some countries (including the United States) can no longer buy from AliExpress because of its unfriendly return policy towards stores.

Probably it's indeed the same for A40.
Perhaps somebody having A40 could confirm.

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?

thanks
