Edit : My E1DA 9038S balanced DAC/AMP has shipped...yes !...looking forward to everything balanced brings to planars...better imaging...separation.....PRaT....bass texture/tightness...

Balanced does NONE of those things. It provides more power because of the "hot and cold" signals and it's less noisy because it's able to hide the noise in the 2nd signal. If there is any of difference than that it is because the manufacturer made one port better than the other. But balanced connections do not provide any of those things you think you are getting.

Here is a decent read on it..

Yes, read all that before, but it always seems like that is the plain difference A/B, so I'll put it down to ports.
(We can at least carry one or two faulty ideas about audio science..haha)

Regards balanced and planars - balanced doesn't inherently bring any of those qualities, but it does bring 4x the output power which many headphones (planars in particular) do benefit from and you may notice improvements depending on how hungry the cans are.

Thankks. Perfect .

Please let us know how the Audirect Lightning to USB C cable works with your Iphone and the 9038S.. Recent IOS updates render most non-MFI cables useless these days. Thanks.

Audirect Lightning to USB C cable works with Iphone and Beam on IOS 13.1

i just order 9038s for my cl2. As the audioscience data, this looks like the cleanest sound for this price and this form factor. The only thing i scared is the practicality. Idk how to make sure everyhting will be controlled in terms of volume.

9038s is too darn powerful for my iems, I almost muted music app, the sound still louder than the level I'm used to.

Wow this sounds like it may accidentally fry drivers in a sensitive IEMs if we are not careful with the volume.

Ar you referring to the just released version 2 of the dac/amp on setting 4 - for high sensitivity IEMs, or the first version that does not have the new high-sensitivity IEM setting ?

The 2nd version.

But from here I see Ivan is developing a new model with Volume control, maybe IEM users better wait a bit longer?

Yes, it's THIS version... It's still in testing... I posted it on the last page. Not sure about Volume control but it can be powered by a phone, no need for a extra battery like the current versions.

According to multiple headfiers requests: 3.5mm jack unbalanced output DAC+HPA 600mW@16ohm in the same case like #9038S with additional 5th operation mode

The s version can be powered by phone too right?
