Hi. How does your DX340 get along with the Noire X?

I literally went through the effort of logging in after a decade of not logging into my account here, password reset etc.. to answer this question, I just got my dx340 yesterday and the noire x headphones from bloom.. they sound fantastic. Not sure if this has been answered since I haven’t made it past page 246 yet on this thread.

My LHY 80W LPSU just arrived!

Thing is solid and very dense due to it's smaller size.

Very high quality (just like Gustard quality). I've owned LHY stuff in the past and have always been wowed by the quality.


For now I will use the included aviator cable (with the adaptor I bought from Amazon) since my aviator to 3.5x1.35mm cable hasn't arrived yet.

(Despite what the Aliexpress listing said, the unit DOES come with an AC power cable.)

Can't wait to hook it up!

It’s very much appreciated. Congrats and welcome back!

Look forward to your impressions. Did you go with the premium or standard version?

3Max vs. DX340 tonight… the 3Max is non-modded and sounds best via Neutron. The DX340 is now fully -in and the UAPP is better than Neutron for my taste.

DX340 sounds more powerful, wider, bigger, better layered and just more realistic than its older brother. It’s not night & day difference, but I cannot ignore the edge the DX340 has over the 3Max. The thing is, it’s Friday night here and I am pretty tired after a hard week at work. I definitely need to repeat the comparison before drawing final conclusions. Love both DAPs anyway.

The EA4 is coming on Monday, so the dice will be rolled again in any case.

You might as well take next week off of work. A multitude of adjustability on the EA4 paired with FPGA 3,0 harmonic adjustments and desktop super gain mode on the 340.

Note: 340 Max LO voltage via 4.4 Bal out is 2 Vrms, which is the minimum range LO signal for EA4. But I think the 340 LO signal will be better than 340 PO to the EA4, unless you see an advantage with double amping.

Did anyone here tried DC in with IFI ipowerX 12v and a proper LPSU to be able to give a short comparison sound-wise?

Double amping is not a drama. To me at least. Been there in the past with my trusty Calyx M and a C9. It might hurt the purist emotion, though. The DX340 doesn’t require external amping to shine, we know that, but my Romi BX2Pro does bring it where it truly belongs.

Many thanks for the info regarding the voltage topic.

We will see how things turn out.

Premium because why not.

So I had a brief time comparing it to the stock 12V DC plug, there may be a very small difference in "sound quality" on AMP15 between the LPSU and the 12V DC plug, perhaps there is slightly better dynamics or "weight" to the music as I can hear but it's hard to make anything out. The more obvious difference is that the LPSU is dead quiet compared to the 12V DC plug or a powerbank.

Maybe changes would be more drastic if I equipped an ultra beefy thick AC power cable or used a monsterously thick aviator to 3.5x1.35mm cable but I'm happy with my set up at the moment.

Would I recommend everyone buy the LHY LPSU? For it's price it's probably not neccessary and overkill since AMP15 isn't going to scale with a beefier LPSU, it's just gonna draw 12V from the LPSU and thats it. I think the FiiO LPSU or something cheaper would be a better buy imo.

The Lavricables Grand iem cables for my Astroliths were probably the biggest upgrade aside from ear tips that had a big effect on presentation, dynamic range and soundstage ect.
Ever since I used these cables, I seem to gravitate towards the D3, D4 & D5 filters on the DX340 as of late. It's such a big change in dynamic range, soundstage depth/width, separation, imaging and texture. I think I will always prefer pure silver 20awg cables for my IEMs from now on!

Not all LPSU is the same. If your LPSU cant tell much from your walwart, I recommend a return on it. Especially when you can hear filters effects and cables....and even music app such as UAPP vs Neutron vs Mango... Changing the PowerCord will not cut it, and that much I can tell

Trust me when I say Dx340 "Will Scale" with beefier LPSU. If the differences between filters is 30%, then walwart is also 30%, a powerbank 12V is 40% and a good/beefier LPSU is 100%

I normally dont tell people to trust me, but since you come to the conclusion that quickly, I say, you havent encountered a good LPSU yet. This LHY you have is probably just as good as Fiio one

 

[Daniel59]

The more obvious difference is that the LPSU is dead quiet compared to the 12V DC plug or a powerbank.

So, the powerbank option can be just as noisy as a 12V wall wart?

Depends on Bank. They are all using a switching LDO lines to regulate voltage. Some can be noisier than others. They are not all the same either.

Remember, the reasons why portable players dont want to boost up a voltage too much from too little of a source like boosting to 12V from 3.5V. That is because of all the trade offs from current/voltage and switching actions of the transistors. It is just a physic limitation thing for now.

But any LPSU would be more quiet due to the fact that they are pure 12V from 120V source

I dunno, maybe I need more time comparing them together. I'm sure I noticed slightly better soundstage and dynamics with the LPSU vs the wall wart but it's not night and day difference from what I can hear so far.
Does LPSU need burn in ?

I did notice though that the DX340 still glitches with lingering hissing when swapping plugs, plugging in and unplugging 12V cables seems to glitch the Super Gain Mode for some reason which is a bit annoying. If I wait long enough like 10 seconds and then resume playback on UAPP and Neutron the hissing goes away otherwise I would have to reboot the DX340.

Yes. Understood. I was more implying that since a power bank is not attached to one’s home AC, it wouldn’t incur the same noise as a wall wart can/will. But, like you’re stating, there are more forms of noise than 60/50 Hz sine wave power line noise.
