Can you give your impressions on the sound quality between the SP1000 Cu and the WM1Z (with the new 2.0 firmware update which others are saying changes the sound signature of the Walkman)?
How many hours do you have on the WM1Z? Sony says that it takes 200 hours to get to maximum sound quality.
Appreciate your thoughts as I try to decide between the SP1000 Cu and the WM1Z.
Yep, I wrote a quick review for a forum in Polish, a quick translation, pardon for rookie English. Before we start, I'll only answer that I have probably only about 50h on my WM1Z and installed 2.0 roughly from the start, so had no time to analyze firmware differences unfortunately - however it sounded great from the start. So, let's quote myself:
Today, we tested WM1Z and SP1000 Cu with my wife on several different tracks, genres and headphones. I'm afraid that 1Z has better not only the battery
or rather the design (class D), but also has something else. He has a soul. To summarize our findings, you have:
WM1Z: analogue poetry from the country of the rising sun and blooming cherry
Ultima Cu: Korean technology excellence
I am saying that my WM1Z is not fully warmed up. It has dozens of hours of heat on the counter. The manufacturer is advising 200h of warming, and users report 500h ... What will it be? We'll see. From the beginning, however, my WM1Z had pretty highs, very delicate, never rough on the ears.
Secondly, I note that both devices are great. There is no way that one kills the other or vice versa. They have a slightly different character; and both represent an idea of perfection. Both are in my opinion competitive to the level set by Hugo 2. For example, as proof of this thesis, the Shure KSE1500 play great with Hugo2, but I prefer it with the Ultima line out, because then I hear the sound equally transparent, slightly different with slightly backward mids, but with less noise, which is more important when listening to classical.
A little and I regret, and I'm surprised that I did not appreciate WM1Z before. I beat myself in the chest. I listened to it on AVS 2016 and it did not impress me, because he had a few songs on device only, and WM1Z did not drive my earphones from that period and I could not even verify really how it sounds.
Even on CanJam London it's Ultima SS that impressed me, and WM1Z I heard that it is just "good" and better than WM1A. Now I understand why. Because this device does not play "phenomenally". Your hat will not fall off your head. 1Z plays just fine, but subtle. This is a
refined sound that never attacks your ear.
At CanJam I saw for the first time his black case, which is remarkably designed. And there's not much information about it on the web. Perfectly protects the device while exposing the buttons and emphasizing the look of the device, rather than covering it completely, like the Ultima case, which in addition almost does not protect (exposed upper right corner of the device).
But the best in WM1Z is one thing:
ANALOGUE. Listening to WM1Z, I was took back more than 20 years before, when I listened to Walkman and my first tapes. WM1Z has a similar analogue "noise" on the sound, which reminded me of cassettes - and that softness, which I had long forgotten, and had existed only in imagination or dreams. I really went back in time. This is subtle and we will not hear it on CanJam or AVS, listening briefly on accidental headphones.
WM1Z also catches the beautiful synergy with my Final Lab II on classical or acoustic music, it is pure poetry.
Overall I am delighted. In favor of the device is that it's also much lower price than the Ultima, and the hardware is on the same shelf.
Cons are two or three.
- No wifi, no Tidal, only files.
- A special Sony plug for charging or connecting your PC, you lose the cable and you have a problem, requires 1-2 pcs to stock up.
- Limiting the volume, though on the internet hangs instructions how to remove this, it requires Windows / Linux or virtual machine eg Parallels and takes some time to do it...
- ... and even if we remove the limit, it only consists in the fact that in the menu we get access to increased boost of the amplifier - and so - useful for driving planes or older dynamics, although I do not know if it will work out, so this power will not be much ...
- ... and so with the Shure KSE1500 does not cope, on the acoustic music we feel too low volume, and the Shure KSE1500 amplifier above a certain level causes distortion, because ...
- ... WM1Z has no analogue line-out, we can just release the headphone or digital signal turned up.
In summary, this is a DAP rather for a mobile headset
not to drive LCD-4
It holds 25+ hours on the battery for that. I does not drive the best IEMs in the world (KSE1500), but when I drive them (when I let go of more loud music, ie studio, not acoustic), it is still superb.
Both Ultima and WM1Z are great equipment, I emphasize it at the end. Both play better than many stationary sets. Let everyone judge what he likes better.
// Sorry again for the Google Translator English, I had only that much time to straighten this up.
To sum this up, if I had to choose one, I would choose WM1Z without hestitation. Especially with the price difference.
Then I would try to make it work with KSE1500
EDIT:
I have to correct myself. My test was probably on some very quiet music, probably it was "Requiem for a friend" by Preisner, where there are often parts with only one instrument in a huge space. Then, truly, WM1Z output may be not enough. But, for most classical music, it will be enough. I listened all day today and KSE1500 pairs beautifully with WM1Z. I've managed to find another album with such a problem, again: only organs, recorded from many feet away, an old master tape moved into DSD files. Again WM1Z was not loud enough and KSE1500 was on a brink of distortion. But I have to correct myself, that for most music, WM1Z is enough to drive KSE1500.
