I have [active speakers] with only balanced XLR inputs. I need a DAC that has [balanced] outputs .... I currently use an [unbalanced] DAC and RCA to XLR adapter, which I'd prefer to stop using.
You don't mention the listening environment and listening volume levels.
Most likely, you don't "need" to change your source from unbalanced to balanced since (a) the available gain on the speakers more than enough to cover the difference between 2V vs. 4V of nominal input level that typically comes with upgrading to a balanced output device, (b) a properly wired RCA to XLR cable will still deliver some level of noise rejection anyway, and (c) you most likely do not have noise interference issues affecting the cables from your DAC/Amp amplifier to your speakers in the first place.
That said, longer cable runs to active speakers / subwoofers is one of the cases where moving to a balanced output source for maximum noise rejection (CMRR) is
most likely to have an actual benefit in a home setting... though that is still most likely not the case for you (and it wasn't for me).
However, the "I
want a DAC/Amp that has balanced outputs to my active speakers" is a strong desire indeed.
Which is why I also have an RME ADI-2 Pro FS R that I didn't "need" but absolutely love!!!
I'm not sure I care for the 1/4" balanced outputs over actual 3-pin XLR.
As others note, TRS and XLR are interchangeable connectors for balanced audio. In a home environment, there is absolute no difference or reason to prefer one over the other. The only caveat here is to avoid using single-body
XLR->TRS Adapters since the added "weight on a lever" is not good for the TRS jack.
I bought a RME ADI-2-Pro FS R BE
This will be an audio purchase you will never regret.
Some had mentioned it can run very hot, but perhaps that is only when several inputs and outputs are being used simultaneously.
My experience is that it will feel hot (though not as hot as the TOPPING A30 Pro). But RME devices are engineered for the level of heat they produce, and will provide decades of service in demanding professional environments. Personally, I added a bit more clearance between the ADI-2 Pro and the solid shelf above it, and also enabled the auto-off option... but neither of those steps were necessary.
One last note: the auto ref feature on the RME ADI-2 series is a fantastic capability and completely removes the need to ever worry about having to upgrade source components from "consumer" nominal line levels (2V) to "professional" nominal line levels (4V to 15V). And, it works seamlessly in a mix environment where some inputs are 2V and other inputs are 4V to 15V.
I've never used pro-geared equipment, so the need to turn the plug to lock into place was something new. (edit: I bought the unit used, so the sticker explaining the locking nature of the plug was no longer there.)
