FiiO Q7 Portable Desktop-Class DAC and Headphone Amplifier Discussion & Impressions Thread
May 11, 2022 at 3:13 AM Post #121 of 714
I don't like where this is going. Looks like Fiio is cutting corners too much. This will not be truly balanced DAC if only one chip will be used. Also what happened to the original ambient light that was discussed earlier ? If that one on the picture is the way you're going with then you can just drop it completely. Will the display be at least OLED ? And you want up to 1000 for this ? How is it justified ?

ES9038 Pro supports 8 channels so no need for two DAC chips for truly balanced config. Two 9038 Pro DAC chips would be an overkill for portable device IMO.
I don't know if they are going to use one or two DAC chips but rest assured that even one piece of ES9038 Pro can be configured for a fully balanced and differential design starting from its output all the way up to the amplifier stage.
Correct, FiiO confirmed a few posts back that they are going to use single DAC chip to reduce the costs.

I guess there is a reason why manufacturers are going for 2 DAC chips even in single ended implementations. Also I don't really understand why force desktop 8 channels DAC into small device used for headphones. It only brings issues with cooling etc. They should focus more on the quality of implementation. Why not to use 2x ES9068A instead ? I'd like to hear that difference. BTW does anyone know of new DACs with ES9068A ?

How new?
SMSL - Aoshida DO200 is new enough?
Topping DX5 maybe?

I don't think OLED are particularly useful in decoders like Q7,
Q7's strength should be its decoding ability 、Full range of interfaces and his output power.

K9 will use 2x ES9068A

“Portable desktop” is exactly what I’m looking for since I’m primarily a laptop user. This looks like it’s going to basically be a portable version of the K9. Looking forward to it.

Yes,According to our understanding, the Q7 is very competitive.
