post #601 of 1488

John mentioned that MQA was not supported by the Mojo and wouldn't be future upgraded as the system is locked down, but did say that could be done in Software so its likely the Poly would receive the MQA file to it over wifi then do the decoding to feed as a PCM stream to the Mojo. He has stated the Poly is software upgradeable over WiFi.  The file could transfer in its base format over to the Poly into a local buffer maybe and the Poly processor does the number crunching to feed the Mojo.

Sensitivity for the HD800 is 102 dB SPL/1Vrms, impedance is 300Ohm. AK100 output impedance is 20Ohm and max level is 1.5Vrms. Just do the math... for 104dB SPL you would need an output level of about 1.343Vrms (105 dB SPL would be ~1.507Vrms). 

 

The math isn't the point... the point is that yes, an AK100 is a more than viable solution under the conditions you have presented. 


My dear friend. Thats exactly why I enjoy to read but not to write on Head-Fi. The math doesn't matter.

 

Real live experience is more important.

 

Do you understand how much 1.5 Vrms is in mW? Did you hear a HD 800 on a AK 100?

 

I did, and it's sounds terrible.

You would have to listen to your offline tracks on Tidal and other streaming services, and whatever files you may have on your phone locally, since connecting to the Poly's WiFi network would disable your 4G connection, for example.

Yep, that's another drawback.

nope that's not what I'm trying to convey and I'm sorry that I'm not making myself more clear... I'll try again.

Lets forget about Airplay for a second. It's only relevant for iOS devices.

As far as I know (I work in the consumer audio business), all audio devices that simultaneously support streaming devices and android devices, grab the streaming audio directly from the cloud. No audio is being sent from your phone/tablet to your audio device, just controls (e.g. Play Adel Hello from time 0:00:05). Some of he platforms that exist that allow that kind of UX are Spotify Connect, Cast for Audio and Allplay. Those platforms are supported by a wide array of different chipsets from companies like Mediatek.

DLNA cannot be used to stream audio from your Spotify app on your phone to an audio device that supports dlna. So... the big question is, does Poly support local streaming services on a built in SoC, if not... Bluetooth is your only route when using android.

Just because you don't like it, doesn't mean a) that it is false or b) that others don't either. 

 

Again, you continue to miss the point that there are alternatives available that have a larger feature set.

I did read all your comments. The chromecast, etc.

 

I'm here for a long time (doesn't matter my registry date), to enjoy, not to discuss. 

 

If you like to proof something, please go ahead, but without me.

 

Google my avatar and you may understand.

 

I'm here to talk about the Poly and nothing else.

 

I did misunderstood the idea before, but now I'm understand.

 

[Mod Comment] - removed personal attack

I think you misunderstand. My post was not to attack anyone, nor is it to convince someone of an alternative I have chosen (I would never buy an AK100). Someone stated that you need a TOTL DAP and a Mojo/amp... I simply provided evidence for why it's not true.

...You've still sorta lost me with the tech :blink:

 

But all I can say is that it's been mentioned that Android would be able to support a WiFi connection to the Poly for lossless audio. I tend to ignore any AirPlay features anyways since they don't apply to me as I don't use an iPhone. Unless, that is, I misunderstood that somewhere, and if I recall correctly the source was directly from Chord (not going to search back now though).

 

I would be truly surprised if only Bluetooth was supported for Android.

Will be most interested to see the User Manual on Chord's site. Will give a better idea of full functionality. Wonder if the extended case will be available same time in March.

post #609 of 1488

Has anyone had experience with the Focal Elear and Mojo. Considering these cans but was wondering about the pairing.

There meant to be including it free with the Poly but not sure if that's only a limited time offer.

Actually having done some more searching, there are some workarounds that do allow some form of streaming using DLNA. But... it's a workaround not officially supported by the streaming services. The app that continues to be mentioned is BubbleUPNP. This app allows you to access your Tidal account and then stream to DLNA compatible devices as if it was audio locally stored on the phone/tablet. Neat workaround. But... no offline content support and if Tidal/Qobuz or whoever wants to close that door, it's a mouse click away.

 

So... again, using the official Android streaming apps for Tidal/Qobuz/Spotify/..., it looks like your only option will be Bluetooth. Unless Chord comes out to tell us otherwise. No Pressure, Chord guys :D

Yes, it will.

John, When will Chord have the user manuals for Poly and Hugo2 on the web? Will have a much better idea of the device. Looking forward to getting it.

This is the Poly thread. You should look in the Mojo thread: http://www.head-fi.org/t/784602/chord-mojo-dac-amp-faq-in-3rd-post (edit: just looked, there are posts there on the Elear if you search).
