Sidenote: I wonder why there are 2 volume pots?

 
Good question!
Probably one for headphone output, and the other one for line output. Just my guess.

 

[HiFiChris]

My guess is that one of them is the volume potentiometer and the other one is the input selector on that rendered image. Am I right, James?

A potential rival of the Oppo HA2 and Cayin C5DAC! 
Btw, will it work as a DAC/AMP for the Ipod Classic?

Yes！

Yes！

Right! Make sense! Volume and input selector.

sorry not.

James,

I like the DLNA idea. Without it, I would not buy Q5 even if you put 8 channels of DACs there

Bluetooth has improved significantly over the past 5 years, please consider it again. You probably should not make a decision based on a 5-year-old research on digital products.

Creative E5 is a powerful amp/DAC/ADC with Bluetooth. You may learn from their design.

I prefer to have more amp power than that offered by X7, if I am buying an amp/DAC again.

 
1, The SQ of bluetooth is a big problem , also it is quite easy to be disturbed . 
 
2, The output power dedepened on the amp module. 

 

[JamesFiiO]

seems like that dual AK4490 is a reasonable option. 

 

[HiFiChris]

Will the Q5 come with an amp module already included (probably IEM module, like the X7)?

 

[audionewbi]

Why not AKm dac chip?

Yes, go for it!

  seems like that dual AK4490 is a reasonable option. 

yes, very reasonable. would be a great choice, IMO.

like HiFiChris, I'd also like to know if it comes with an amp module already mounted...
and also the estimated release date.

I would have been more interested in dual ESS9018 because it could have been with better treble, but I think that dual AK 4490 is fine too.
 
I still wonder how much the amp modules are going to cost? 
 
If you make a module with the op-amps of Fiio E12a, I think that it is going to sell like hot cakes

  Remember that full digital volume control can only work by eating into the digital bit of the music. For example, every -6dB equals to the loss of one bit. Think of the effect it will have if you are listening to a 16bit file with low volume, you could very well listening to 12bit music at the end. On the other hand, PGA2311 is actually still an analog volume control, but only the volume adjustment is digitally controlled. Therefore it offers near perfect volume match on both channel as well as very precise steps (0.5dB), but without any reduction of the digital resolution. It is pretty much an combination of the best of both world.
 
The actual working is usually like this: an small ADC is monitoring the pot, when the pot turns, the ADC converts the actual turning into digital signal and send it to PGA2311, then the chip sets the volume accordingly using the tiny resistors network inside the chip.

Found that interesting. Thanks.

SQ is pretty darn good with latest Bluetooth implementations.

Signal dropout is a certainly a concern, however. I'm testing a Bluetooth amp right now, and signal does cut out sometimes when my iPhone fetches data.
