Chord Electronics ☆ Poly ☆ (wireless & microSD module for Mojo) ☆★►USEFUL INFO on 1st PAGE!!◄★☆

[miketlse]

I received a new pair mojo2 and poly, one that didn’t die after 1,5 day.

Got it working with a 4 year old router because it did not support my 2 year dual wifi mesh network. It was a pain though!! Man man!

Can someone explain, why it everything sounds better through poly streamed than for example connected to my astell
And kern as a transport (usb connected)

I want to understand what the poly does different. (I meant that seriously)

Perhaps view things from the point of a journey. Yes this is a phrase that has become 'business speak' and which I am not enthusiastic about.
Anyway, if you search the early Mojo thread posts, there were quite a few owners who tried AK daps as a wired source for the Mojo.
AK daps proved a good wired source for the OG Mojo.
I think that this was demonstrated beyond the point of reasonable dispute.

What does the Mojopoly do better?
There were many posts about what was the best cable between a phone (or dap) and the Mojo.
There were early posts in the Mojo thread about the potential for earphone cables to pick up RFI.
If anything the research since then has highlighted the importance of reducing the impact of RFI on the analog sections of DACS.
The Poly (and it could be argued the 2Go also) enables a connection from the source (Poly) and the DAC (Mojo) which eliminates the cable which can attract RFI.

I noticed that the mojo2 with the poly sounded better that with the se180 connected usb as transport (not bad ofcourse!, but poly just sounded better)

I was really curious what poly did different, but think it have to be more than cable alone shouldn’t?

The Poly and 2Go both have the potential to remove the interconnect cable which attracts RFI.

However this doesn't eliminate the difficulties inherent in the music player apps that transmit the music data to the Poly/2Go.
Nevertheless this doesn't remove my surprise that none of the Chord thread posters have decided to post the code to create an open-source competitor, that could feed music data to Mojo2/2Go.

My theory is that nobody sane wants to support such broken design as Poly is with almost retro like capabilities with own source code. You need to find someone who loves Poly so much that he/she can spend his time trying to overcome all the limitation and possible idiosyncratics. Nobody like to get beaten when their code doesn't work due to bad hardware design. Can speak about 2Go since I have 0 experience with it. Last but not least those who are looking for a real challange can find it elsewhere

Overall this is probably a bad news for many Poly owners, including me.

I got it working (sent to me to test) because the other one was broken).

It annoys me to say, if it works it sounds insanely good, having hard time to choose between smooth detailled mojo2+poly or pinpoint precision with a tint of smoothnes of the se180+sem4

I would love a combination of the two in a small formfactor, would that be something like a sp2000 or sp3000 maybe?

I used the find and replace of the MacOS text editor for thr Shanling. You think this is possible with the Poly?

I would think so as long as the correct format is followed.

@Daniel Johnston sure it is - after all those are plain, flat text files with proper file extension. Just like @rlw6534 said. It is just so cumbersome IMHO. Currently I'm redoing my Poly SD card playlists with M.A.L.P. base on this Chord tutorial:

It works but if you are going to create large number of playlists with complex directory structure on SD card than it maybe tedious task. My tip is to first make a very clean and well organise directory structure on the SD card itself, before using any 3rd party tool for playlist creation.

I am using MALP from my laptop hotspot and it works flawlessly.

Chord support got back to me on the issue of the yellow flashing Pstatus indicator. They don’t have a ready explanation, my dealer is now supposed to take a look at it. Ultimately it will end up being sent to the UK for repair, I’m almost certain.

Found this post in the link below which could be useful (VLC is a must have free software on any platform - can come in very handy for many things and looks like this may be one of them). I have not tried what they recommend yet but hopefully will find some time soon. Steps seem very straight forward so I would be surprised if it does not work.

Yeah, I normally play by album or folder (which GoFigure can't do) so I generally only use playlists for certain scenarios like genre collections. M.A.L.P and Rigelian both work fine for this. My biggest issue is that Poly doesn't see my existing playlists due to the different format and location, so I have to recreate them.

 

[WilOverton]

After reading about it on here yesterday, I set up Cantata and it works fine, connects to the Poly and reads and writes playlists to it without any problem. A lot easier than having to transfer the card from the Poly to the computer and manually edit the list with something like BBEdit or other text editor. Not sure how much I'll use it, though. Any playlists I create tend to be done on the fly where I'll be listening to something and decide I want it on a PL. It's just a couple of taps, then to add it in Rigelian. What I'd really like is a way of adding music without having to keep taking the SD card in and out of the Poly. I'm sure that can't be good for it over time.

Maybe I should just bite the bullet and start using Roon.

I also find Mojo2+Poly when Poly is in hotsptot mode sounds noticably better than Mojo2 connected to iphone via usbc cable. I am surprised by that because I did not really buy into RFI playing that much of a role impacting sound (read many posts about that over the years on this forum about various devices) until now that I have Mojo2 and Poly. Still wandering if this may not be somehow due to MPD software in Poly hotspot mode just being simpler software implementation vs streaming data from outside the Mojo2+Poly bundle itself (anything in direction from phone to Poly whether wired or wireless). Simple is usually better since processors would be presumably less stressed/tasked so could that be the reason for difference in sound?

Thanks.

That is what I was referring to--using iTunes (or VLC in the linked site) to make the playlists since it does a good job reading metadata accurately. Then export it to M3U compatible format. Use the find and replace in macOS text editor to change the root path to whatever poly uses. That takes seconds to do. The majority of work is in the playlist creation. Any new album additions done via Rigelian, etc...

The above method what we have to do with the budget level Shanling players. It's not really hard or time consuming.outside of the playlist curating. I do like Cantata, but MPD is a little screwy with metadata. I haven't tried Rigelian. I'll give that a go.

Yes. Having the extended genre and radio function worth it. I don't really use playlists at home much because Roon radio is excellent. I'm trying to find a better portable solution. Roon ARC is excellent, but you can't easily use Poly. You'll have to connect Mojo2 to your phone or a DAP. I suppose you could airplay if you use iOS.

@WillOverton: Roon basically makes for me Poly useless on the go.

The reason I went down the Poly path was a compact size of Mojo/Mojo2 + Poly (it is shorter than ifi micro iDSD for example) and could be (in theory) great companion when traveling or commuting. Roon requires Roon core so either you need one with you or you need Roon ARC - none of the solutions could really work for me. Poly + Roon is a great combo when I'm at home, in fact the only setup that always worked for me with Poly has been Roon so far.
