We've discussed this topic to death at the ZX2 thread,apart from different hearing which is the least issue here unless you like to listen ear splittingly loud or silent,what matters is the juice each headfone/iem requires to reach sufficient,loud enough volume.You know that 50% means nothing with sound adjustment disabled as the vol stops increasing at around 60%.He's got the ie800 which needs a lot of juice,around 55-60% with sound adjustment off or 90 -100% vol at stock regarding eu ZX2.Funnily enough it's the same with my old eu nw f805 which is 5mw as opposed to 15mw zx2,around 90% with ie800.The eu WM1Z with the 60/240mw is gonna reach 90% too,the amp becomes irrelevant with the cap.

Ugh,the thought of someone unknowingly buying a $3200 device in Europe and won't be able to drive properly a dynamic iem,it will go down as the biggest travesty in music history.
It's not Sony's fault the eu laws compel Sony to volume cap their devices but I think you can uncap the devices with a bit of effort

Live in the in EU. Bought a ZX300. Invested like 10 minutes into uncapping it. I would advice you to do the same or buying a US or Asia import device. I have a WM1A US import on the way but will probably still change the region code to the Asia one because it has more features. This law from the EU is really ridiculous but manufacturers have to implement it if they want to sell units in the EU.

I have an uncapped EU version too, but I figured I don’t need to enable high gain for the headphones and IEMs I have. So both the Focal Utopia (balanced output) and the Sony MDR-EX1000 (unbalanced output) go plenty loud on low gain. When I had the QP2R, I always had to use high gain and high bias on the balanced output to reach desirable volume levels (and quality of sound). The WM1A drives the cans and the IEMs effortlessly.

One year ago, i went to a shop in Seoul to compare with AK380 and SP1000 with nw-wm1z. The sony nw-wm1z sound like crap. No air (no 3-d stereo imaging)compare to AK. But last week, i went to same shop, listening to it with new firmware. Hey it is pretty decent, now an upgrade from my AK380. It sound different from SP1000. It might have more detail than both. I think i will look at second hand market and seek one. it got the 4.4mm balance which can work with my ar-h1 with special cable.
Sony engineer who play around the firmware really did a good job. They turn crap to top class DAP. Give them a raise.

Is it weird that i like using the jvc marshmallows with comply tips than the acoustune hs1551 when im using the wm1a? It just sounds way more spacious on the jvc than on the acoustunes.

So true. The early firmware was a bottle-neck. I purchased one days before FW 2.0 came out, and noticed a huge set of sonic improvements even though my particular unit had only just begun burn-in. The 1Z with 3.0 or 3.01 is a marvelous improvement to my ears.

And.....who knew? Some folks still like the early firmware sound and I respect that. But 3.01 sounds like heaven to me?

Yup. The details of 3.01 and the organic sound makes me like it very much on my Acoustune HS1650CU.

It's normal. Some IEM just got a better synergy.

I upgraded my 1551 with a Leonidas cable. And now with my HS1650CU.

The early firmware = very clear audio but zero imaging. Why would i pay 3000 for mono player. When it was released, it was number 1 detail DAP.
Indeed, the new firmware is great. One year ago, i do not understand why they charged so much. Night and day compare to SP1000. Now, i cannot tell which one i like better. Sony has more detail less imaging compare to SP1000. So, up to personal presence which is better.

By the way, i listened to WM1A too. Pretty close and impressive too. At fraction of the price. I am not looking to downgrade from my AK380. But if i am in market for cheap DAP now. I would give WM1A a serious listen.

On the high end front, i am 100% sure DAP will improve by leaps and bounds. I have a cheap hifi DAC at home, exogal comet on my stereo, it has more detail, better bass than AK380. Comet is nothing compare to all the high end DAC introduced in 2018. The technology will slowly trickle into DAP. Who will push the next breakthrough DAP, AK or Sony? I am excited to hear 2019/2020 DAP.

Has anyone heard the differences between the 1z/1a is it a really big difference? I am thinking of getting a DAP for the CA Solaris, the 1z just makes me weep so much.. The 1A is reasonable, but was wondering if it is heavily compromised when compared to the 1z.
