I have tried both suggestions and must conclude that this device is really slow and can be laggy especially when using streaming services. I have indeed the latetst firmware that may be even slower.
You are correct. Its not fast like a smart phone, and i think the processor they used was a poor choice. It is slow and not powerful enough for this device and features.
One reason a lot of other manufactures start using snapdragon 600 series up. I have had a lot of Ak devices and they have all been slow compared to others. I hear the newer models finally picked up the pace a bit but at a steep cost.
Lately I use the CA1000 mainly connected to my stereo and use my other daps for everything else. The ease of use with streaming apps and on device music files is just faster using my other daps. Most have the android system that allows me to install whatever i want without sideload or via services.
