I am not sure if it is safe to connect a balanced output to a common ground RCA input.

Guys! The Apple Music v3.6beta is available on APKmirror. Works nicely on the DX300

hi, Amp12 arrived.. can anyone recommend a 4.4-> RCA adapter I could use to connect it to HP amp?

thanks!

Question for @Paul - iBasso

Would like to page Dr. @Paul - iBasso on this question as well please

Haven't been able to find a straight answer on threads - most say balanced output to single ended input is a no-no, but others point to 4.4mm possibly not having an issue with that due to the 5th pin for grounding (or something along those lines), but also depends on implementation?

Assuming amp12 has a connection to ground, it's possible to construct a proper 4.4mm to RCA cable.

I'm not sure who a reliable vendor is though.

It is important to make sure that the inverted signal pins of balanced output is not shorted to ground. I read that some devices are able to cope with that but it does not sound very safe to me.

So I know what the individual words you wrote meant but not what it all means together as I have no technical sound/electrical engineering knowledge

Would that be something on the cable, source, amp side, or all of the above? How does one check for outroinverted balanced shorting paths on the ground?

Never could use my DX300 as a transport. Same with the DX220. Tried 5 different OTG cables. It would connect 1 out of 10 tries. Great device but this a major flaw.

Which usb dac are you connecting to DX300? I tested with iBasso DC03 (and loaded iBasso UAC app for volume control) and L&P W2, no issues.

Balanced output has the signal (+), its inversion (-) and a ground. The idea is that the same noise is added to the inverted signal, and when at the receiving end the inverted signal is inverted again (so it becomes same as the standart signal) and added to the positive signal, the noise is cancelled. For example, you have a signal +2V, then the inverted signal is -2V. Suppose the signal is propagating on the cable and due to an external noise, 0.5V noise is applied to both + and - signals. So one becomes 2V + 0.5V = 2.5V, and the other becomes -2V + 0.5V = -1.5V. So when you invert the - signal again and add to the + signal. 2.5V + 1.5V = 4V, so the noise is cancelled. For our case, DAPs what is important is that the signal is doubled.

The problem with balanced to RCA connection is that, if the (-) (inverted signal) is connected to ground, it is a short circuit of the half of the amplifier drawing high amounts of current from the amplifier, which can damage it. We have to make sure that, none of R- and L- is shorted to the ground pin:

Thank you
Is APKMirror a paid app? or is there a way to access without paying?

thanks.
i guess i'm not understanding how to use the app properly (despite the "how do I use this app" button!). i.e., i don't see how to search for the apple music beta app. don't ant to clog this thread for that, tho. happy to wait for the official release
thanky you

I received a DX300 today even though I was unsure about the size and sat on the fence for quite some time. It is big but a lovely looking player that feels great in the hand, just a shame about the bizzare volume wheel design. Not the end of the world though. Was lucky enough to get one with the MK1 Amp11 too. I must say, I'm impressed how far iBasso have come with regards to the OS, it's so much smoother than the DX90 and DX200ti, my only other 2 iBasso DAPs. Really nice to use.

I'm still in shock with regards to the sound, I've never heard a player so natural sounding (using D5 filter). Just coming from the M8, which was superb, I wasn't expecting it to sound as good but I'm enjoying it so much more. The soundstage/imaging as well is jaw-droppingly good with sound all around you, you're truly engulfed. It's quite a feat when the signature is on the warmer side of things yet still transparent with great clarity. Bass hits hard and gorgeous mids too. I thought I made a big mistake selling my M8 but that was soon dispelled. The player just sounds out of this world with the Fibae 7 and it only has 50 hours on it.

I'm quite excited to see what comes out on the amp side, may look into Amp12 soon.

Why risk it.
