I have a love/hate relationship with DAPs. I like the convenience of physical buttons, ease of use and more power compared to your average phone, but I certainly, at no point, do I believe is giving me better sound quality. Not audibly, at least. I'm pretty convinced that anything other than the entry level DAPs are a scam if their selling point is better sound quality. However, I'm just a newb at this. So, is there any evidence whatsoever that ultra expensive DAPs like the A&K, can do anything (soundwise) that you can't do with a phone and a cheap amp?
