It depends on what you listen to, if you listen to pre-loudness war music with wide dynamic range, the lack of power becomes somewhat obvious as the details aren't quite present/forward as they should be. Would most people only listening to modern music notice? I somewhat doubt so. In fact the NW-WM1A should be powerful enough to drive the IER-Z1R (but certainly not the MDR-Z1R!) in most scenarios.
Power isn't only about volume output, this is why there are both impedance and sensitivity measurements, in fact low impedance devices (such as what good IEMs would be) require higher current (but lower voltage) to drive.
About the difference of power output between the NW-ZX300 and the NW-WM1A/Z, it would be worthwhile if it was 50mW@32Ohms, as it turns out it's 50mW@16Ohms, which is quite negligible.
That said, the lack of power output on Sony Walkman DAPs contributes to their long battery life, which is one of the most interesting point of Sony DAPs. It's still much an improvement compared to what we used to get on the NW-ZX2 and earlier Sony devices.
Quite frankly, if hard to drive listening apparatus is what you are keen on listening while on the go, Sony DAPs aren't for you. (Unless you fancy carrying an extra portable amplifier, of course.)
I clearly and simply do not belong here and I really don't care. Actually this thread has become so boring. I have no screwing idea what "pre-loudness war music" means. Really? And @rutter hijacking pages of this thread? Really??? Ooops my ears are ringing. I need to stop. But I'll end with the z1r rocks, and if it's not for you move on. It's that simple.
Thanks for the advice guys. I've had a change of heart. Even though the IER-Z1R only requires 1mW to hit 100dB and and 100mW to reach the pain threshold of 120dB I have purchased this power amp to ensure that my IEMs receive the power they require to truly shine and not require 'crazy amounts of EQ' like they require on the truly horrible ZX300.
Sounds amazing so far. Thanks for showing me the light.
I don't think a 3000watt peak amplifier is enough for Z1R. You need at least a 10.000-watt amplifier. This Z1R is power hungry. Only then you can hear the best what Z1R can offer.

Speaking of ear ringing, I'm wondering whether the aforementioned ear rape we were doing is having a lasting effect. I think my ears may be ringing more even without using the IER-Z1R. I didn't notice this before those 30 minutes I was getting the nozzle inside my ear canal and feeling some sounds. Is it possible in that brief period I caused some longer lasting damage that hopefully abates and goes away? It's not like I put myself into an audio-induced coma.

Tinnitus or ear ringing are usually
1) listening sound too loud for a bit too long of an extended period of time,
2) infection, can be sinus or the ear, may even happen from common cold for example
3) side effect of consuming medication.
I think from those three you're most probably hit on the first one., should abate sooner or later. Try lessening those dBs or stop using IEMs for a while, a couple days should do.
If it persist, it's better to get it checked.
If you start having pain and slight loss of hearing (on one side usually), it's most probably an ear infection.
I'm not convinced but this is useful advice nonetheless. A decade ago I think I first noticed tinnitus and that was indeed associated with a medication. Funny thing is it was said it could be permanent. Wasn't warned, but that was ok I suppose.
I'm having a conversation with someone claiming that the absence of a vent makes iems dangerous. We wrote about this before but I'd like a second round of opinions.

Maybe on aircraft when climbing /descending. I wore my Xba-z5 on a train ride from Hessen to Hamburg , the train crossed some tunnels the IEM made these parts of the trip more enjoyable than before with no IEM as I got no air-blocked ear after the train enters the tunnels at 330 km/h
Don't know about the Z1R, but other than Adel IEM's, the ones that are vented usually (some I'm sure is marketing!) are to facilitate full flexing of a Dynamic Driver. Those vents open to the back of the driver and not between the front of the driver and the ear canal.
