I have re-copied all files into the 1.5TB MicroSD, which I have reformatted to NTFS, after knowing that it supports NTFS. The problem seems to be solved as I didn’t face it again anymore. However, ultimately it has show that the N3U has poor exFAT implementation. The exFAT formats with different...

There is a matte plastic protector attached underneath the black one but very loose. I use the glass one instead

Everything is good. BUT it appears that it has a poor compatibility with high capacity memory cards. Using my 2TB AGI Supreme Pro and 1.5TB SanDisk Ultra will cause audio frames drop on my N3U and also the demo unit at the retail store. The weirdest thing is that it happens only when playing...

Can be by album or by track. It has all the basic function a player should possess except for connectivity part and also PCM upsampling and force DSD output.

Is anyone experiencing sudden lag on PCM playback? It appears randomly but it will have increased along with the playback time since its last boot. It only happens when playing PCM at all rates and even for MQA but NOT FOR DSD at any rate. So I don’t think it is a problem of reading speed or...

Around USD $215

It originated in Taiwan but I bought it from Hong Kong market.

The production of the first gen has stopped ever since the launch of the second gen, along with the maintenance service. I have requested to repair my out of warranty 1Z and it was declined around half a year ago.

AGI 2TB Micro-SDXC works like a charm on both 1Z and 1ZM2:L3000:

FLAC is a container, free of charge, like you can use WAV freely, but it has a higher lossless compression rate. MQA on the other hand is a patent-protected proprietary, which is also a container, but you have to pay to use it, in both encoding and decoding ways. So the claim about the JRiver in...

It is about subjectivity on how listeners anticipate the sound to be. On Mathematics perspective, a single error or mistake in billions of data means it is not perfect, that means it is not lossless. On audiophiles' perspective, a rather decent sound means more than perfect bit-to-bit...

For the last question, they are the "MQA encoder" and "original sampling rate" tags in the container's metadata. Many MQA-capable player, which integrate the player-app (if Android/Linux-based) or the interface (like a physical traditional CD player) with the DAC (or the FPGA chip alongside the...

I heard that originally D-type amplifier or its adoptive variants was not that easily qualified for high fidelity playback, at least not before the launch of S-Master, on portable gear wise. The decline of sound quality (noise floor dropping to audible level) will be more significant along with...

This is what I found the most 'Sony Japan' with very unique warm style and clarity of vocals.

As far as I won't stay at a place and listen to the set statically, DMP-Z1-like is never an option, which Ive tried the demo and WM1Z was the option I only used. The MDR-Z1R of mine was sold long time ago and I have tried DX220 as well but not really a good match. On the contrary, IER-Z1R is a...

It was disastrous matching MDRZ1R with WM1Z, even with the modded firmware.

When it comes to WM1Z/A, it isn't. They are technically still better than many.

I honestly don't think this will gonna be a good product. Based on the SoC spec from the Japanese website, in general, any Android machine runs on that 4x Cortex A53 little cores plus a very powerless GPU cannot really satisfy any apps developed majorly based on flagship SoCs. I own a WM1Z and...

Does anyone know how many levels 1Z can unfold a MQA? It displays “MQA 352.8kHz” for the MQA I acquired but I knew that it doesn’t really scan the MQA encoded data for the MQA decoding but rather based on the metadata restored by an official MQA metadata restoration app.

MDR-Z1R on WM1Z performance varies with the firmware installed.

IER-Z1R in high gain via balanced port at around 94, rarely down to 85 for PCM Up to 110 for DSD

Switch off the battery saver and charge it to real 100% This battery indicator has been misleading since the very first day

I have the DX220 with a modified AMP8. Then I bought the WM1Z. Overall the DX220 outdoes the WM1Z in fidelity perspective. But it is relatively much too dry and solid that sounds too harsh to my human ears. Maybe a robot would love it instead. The texture of DX220 is full-bodied, slightly warm...

Mine is June 2020

From WM1Z++ to DMP-Z1 to MKII, the WM1Z has become more and more amazing then ever. The DSEE AI implemented is truly remarkable and fabulous! My songs has never sounded that good before, even for those 24bit but in 44.1 and 48 kHz. I can tell that the DMP-Z1 MKII mod is definitely revolutionary...
