I need some feedback on following observations please, it seems very strange to me:
I tested the Pioneer XDP-100R this week, and, although the sound seemed to be better than my iPhone 6, it was clearly less loud. Low volume output was what put me off Sony ZX-2, and reading the specs of Onkyo DP-X1 / Pioneer XDP-100R (both have the same for SE output, will call them in this post Pion-kyo!) it seemed clear to me that these must be much louder than ZX-2 and iPhone 6:
from

iPhone 6 output:
ZX-2 output: 15mW + 15mW at 16 Ohm
Pion-kyo: 75mW + 75mW at 32 Ohm
According to above specs, I would expect volume output ZX-2 << iPhone << Pionkyo
However, I experienced ZX-2 << Pionkyo < iPhone. To my surprise, I found today this post from a UK user:

This user also complained that his Pioneer has a lower volume than his iPhone!
Another (UK-based) source is the review from avforums, they even say that XDP-100R has less volume than ZX-2...

To round it all up, I also can report from an online chat with the guy from Ohm-Image, based in Singapore: He confirmed that Pioneer and Onkyo had same output volume (in SE), and that they were clearly louder than his iPhone! That is exactly what I would expect when looking at the specs of the devices.
So how to solve this riddle?
I suspect the UK Pioneer devices have an EU imposed volume limit! It will be difficult to test as naturally no one in Asia will buy / test a European version of the Pioneer. I will get my DP-X1 in the next days from Japan, and then hope that really that one is louder. If someone in the meantime has any ideas to find out about volume limit it would be nice to know really..
PS: swap a letter on Pionkyo and you get the little wooden figure that gets a long nose when lying, really hope this double release will not be a Pinokyo story
are the specs incorrect, i.e. don't reflect what is actually available in EU versions?
PS II: I did check the settings of the Pioneer while testing, there is a volume limit setting that was not on, and the gain was set to high already. And there was a warning message about high volume risk when I turned the volume higher. So it seems that EU regulations about warnings have been implemented in the unit I tested. Is it possible that in addition to the software changes (warnings) there was an impact on maximum output volume..?
