if I remember the experiences with the 160 and 220max ..
i would like to give the dx300 150 hours and then form my judgment

Should the dx300 be able to power headphones such as the hd6xx?

When the DX160 and DX220 can, why shouldn't the DX300?
When i trust a table from this forum, you would need 199mW at 300Ohm to drive the HD600 and 167mW at 300Ohm to drive the HD650 (HD6XX) properly.I think should.
Powering is one thing, properly driving with full dynamics, mids body, enough tight and fast bass slam when needed is something else. So they can power them but not drive to their full potential. But MAX can and DX300 also should.

The DX300 would only deliver 132mW at 300Ohm on balanced output, when i am not wrong.

They are talking about this , but what I am curious about is about their tables of howmuch power is needed for a headphones.....That is one weird part where I read some impressions from people who enjoy listening to their HD600/650 driven directly from sources that have fraction of the DX300 output power, but maybe they are referring to driving them loud enough instead of to its full potential. But then, "full potential" is subjective since everybody hears things differently. For the record, I don't have either HD600/650, I'm more IEMs vested
Just from my own personal experience, specs on paper doesn't always align with what I'm hearing. But if we are after the paper spec, iBasso has AMP11 with the following:

Prompted by the higher than expected sensitivity of the HD800, I spent some time creating a spreadsheet of headphones output power required at different level, using their official sensitivity spec to scale with. I thought it was quite interesting after looking at the results, so I'm going to share.
The list of values is based on:
-Power required to reach 120db. (Note, some headphones cannot actually reach this level because it exceeds their max power capability. This is just theoretical.)
-nominal impedance value. (some headphones change impedance depending on frequency, so it wouldn't be accurate in those cases. example: HD800 goes from 300 to almost 650 ohm, so the voltage required to hit the required power output is over 11v in that case, not just the 7 something in the list)

Summary:
This list gives the trend that headphones that we know improve greatly with an amp are near the top of at least one, if not all lists. It also shows that a great amp must be able to at least both deliver high current and high voltage. Otherwise there are headphones that cannot reach their potential. That HE5 is a monster to drive!
On the other side of the spectrum, you can see IEMs so sensitive to the slightest voltage, thus picking up all kinds of noise in the system. And you can clearly see how the ER4S and RE0 behave much like full size headphones, probably devoid of "hiss" problems other IEMs suffer through. This also shows how they don't work so well in headphone jacks of portable players, they do require much power capabilities than other IEMs.
Have you tried the list view instead of album art view? How about restarting the DX300 vs just the Mango Player app?
I enable it, restart the Mango Player but nothing changed on the scroll bar........
Bloom Audio is the best. Actually going to compare the DX300 with the ifi Signature Dac/amp and decide on which one works best with my LCD-3. Haven’t found a DAP yet that does well with it.
