Correct, but did you see the link he shared? It splits 4.4mm plug connection to two separate rca plugs, separating balanced into Left/Right connections.

I afraid that inside power-amped speakers have only 1 ground (mutual). Audio Engine never claims themselves that their products support balanced connection.. In the back of speaker, It has 3.5mm SE Line-in, RCA input and RCA output. By the way, I currently use Audio Engine A5+ as primary.

During Headphone Festival at Japan, Why doesn't iBasso come or start marketing at Japan? In Twitter, I see a Chinese brand that is FiiO only...

I’ve seen iBasso at a few shows in Tokyo

That's what I'm trying to figure out. 4.4mm going to have 2 separate "grounds" going to two separate speakers. Unless speaker grounds are tied together, you are not shorting anything. The problem here is his speakers seems to be active, so I'm not sure about the ground....

Nope, will not work. RCA is always Single ended, therefore within the adapter, the ground is already joined. I have never heard anything to use RCA Balanced to be produced for the market. It is not a standard, unless you made the speakers, or amplifier yourself, and isolate the grounds separately.

Simply put, 4.4mm is 4 poles, and RCA is always 3 poles. You can not reduce the source output signals number, you can only increase it

I don't think you understood what I was saying, you are not going from one balanced Pentaconn connector to another RCA connector. Of course it all depends on how it's wired and as I mentioned, how the manufacturer implemented their active speaker design (in terms of L/R side ground isolation), but that particular adapter has one 4.4mm plug and two RCA connector y-splitter. If you have L+/- wired to one RCA connector and R+/- wired to another RCA connector, this Y-splitter will work as long as that speaker manufacturer has a proper ground isolation so you are going to 2 isolated speakers. It's questionable, but feasible if properly implemented.

But in general, if in doubt - better leave it alone...

@twister6 : I just tought out.. If he buy this 4.4-RCA adaptor, he could test by 1) turn-off his speaker, 2) plug in RCA side to his speaker, 3) do 'Continuity Test' by multi-metter on R-,L- at 4.4 plug side... Then he could know whether it is usable or not.

 

[Whitigir]

RCA, will always be single ended, period. You just can not use a balanced out from the source into any SE input. This example can be found from Headphones. You can not use a female 3.5mm split into 4.4mm Male and connect into the 4.4mm output on the player. The same for any receiving end devices, amplifiers, active speakers....whatever.

They sold DX90, DX80, and HDP-R10 through local agent(authorized importer) in the past. Unfortunately early product of HDP-R10 with numerous bugs caused lost
credibility from the market and since then they are not successful to restore the buggy image. I guess the current importer is not as capable in doing so.
iBasso of 5 years ago is not iBasso now and they should consider change of agency now,

You don’t need to do any continuity test. The L- and R- is connected to ground no RCA. If not, where would it go ? The insulator ?....LOL

L- and R- is active signal Inverted from L+ and R+. You can not connect any Active signals into Ground or...shorting them out

Or may be I don’t know what I am talking about. You are welcome to try it, worse case scenario, you buy new amp module

 

[chaiyuta]

@Whitigir : No, I don't try. I am happy my Audio Engine A5+ connecting with 3.5mm SE Line-in. Just raise something if someone insist to buy and try. And with the above method, I never said that he have to connect to a source (DAC/AMP or DAP) therefore nothing is broken.

Thanks for the clarification. I assume this is the same for two passive speakers (small bookshelf ones)?

Confused because of these

Updated to recent beta firmware.

Hmm not sure what to think about the sound so far.

Hmm. Not sure what to think about the new fw at all....

After use of about an hour or two (pure Mango only) I don't notice improvements or huge changes.
Sound seems to be the same as previous fw, and interface still not as responsive as I would have liked
Havent discovered new features yet (other than that I can't seem to find which Mange version it is on now)

 

[wirefriend]

@Lurker0 - any ETA on your version?

 

[mrmoto050]

"If it aint broke, don't fix it" I am staying with my current FW as I am havin 0 issues.

 

[minsan]

Beta firmware seems to have fixed the random stopping/playing of tracks.

Is this when you use Tidal? Or just Mango playback?
