A small review from myself - I owned both players - very decent devices, with a wonderful sound, which after a little refinement begin to sound even better!
The simplest refinement is a change in the chip of the operational amplifier, which is located in the connector and is changed by a simple interchange. The cost of a good replacement of about 200 rubles for example, personally tested not only by me.LM6172.
The impression from the sound of some spoils the cost and simplicity of the subject, they would be packed in a different case and would have a price of 150 bucks - there would be much more laudatory comments (this is my subjective opinion).

It is unfair that on 4kpk there was no topic for these players.

And what would you advise to take?
The price difference is quite large.
But where is the sound better given the small dorobotki in the form of a replacement op amp?

Prompt detailed instructions (and fix in the top topics) on the combinations of buttons.
Another such question: is it possible to somehow go through the folders on the map or is it still sequential scrolling through each song? Is there any trick?
If the gig card is 32 or higher, then it is quite inconvenient to search for the desired album by flipping tracks (.



Rep: (3)
if you press the "pause" (middle button), the "forward" and "back" buttons switch folders.

It does not work - pause + 1 click Next - throws 1 song in 1 folder on the account, 2-1 click - 2 songs from the 1st folder (, it does not scroll through the folders. MB, I don’t understand something.
For the instructions on the buttons, thanks. : thank_you:

MB, I do not understand something.

Probably, everything worked for me. What format are the files in? Rename the folders without Cyrillic, long names and overlapping.

Which one is better, another is worse. I really liked the sound of the Z1 withLM6172the sound of Z2 is different, but with this opamp also changes for the better. It is better to take Z1 for trial - it will not disappoint, especially:

In the header read the good news and join the project!

Does it support * .m4a files (qaac codec)?



Rep: (49)
Has anyone used as a DAC connected to smart? in players that support usb dac it is possible (Neutron Music Player, etc.), but not in other applications, but I would like to.

Posted 09/09/2017 17:48:

* nxn-zp, It seems like with 3 firmware already supported.



Rep: (35)
It works with phones as a DAC, but not all programs see it. There are several free DAC-enabled programs on the playlist. With a PC as a DAC works fine, Foobar2000 sound is super, richer than on the player itself.



Rep: (10)
Still, which one is better in sound detail? Already ordered a Z1 waiting ...

Bluetooth is not in any.

On another forum, it has long been determined that the stock in Z2 is not the original LM4562. Replacing the original with Chip and Dip, for example, will give an improvement in sound, it has not yet been bought, 220 p in total.

Sori for the lamer question, tell me step by step how to use it with a computer?
Connected via usb, the computer sees a new hi-fi device. Then just listen to music from a computer on it?
Or is there any extra. settings or software? Thanks in advance. : thank_you:



Rep: (7)
1. Connect.
2. Turn on the player (flashes double short flashes)
3. Stick ears or speakers in the player.
4. Use.



Rep: (55)

The player is coming, I think I should order a mustache ....

I was doinghere is this modexcept volume control. The sound becomes very rich and detailed. It even seemed to me too. Oh yeah, and the op-amp was LM6172. For the first modification, it will be enough to change the op amp to the LM6172 and the output capacitors to some larger capacitance, for example, the Jamicon 16V 470uF would be quite enough.

* maxferum Sorry, but the manufacturer is not listed there, but should be NJRC [New Japan Radio]. And the price is alarming.



Rep: (18)
* nid25 , I changed the stock OP275G to AD823AARZ in the low-pass filter (and not only that: D) ​​and the sound has changed for the better. So, to go or not, your business. But before that, I advise you to take a look at the 77th stand of ZiShan Z2 discussion on player.ru.
