FiiO M15 Flagship DAP Android-base Lossless Portable Music Player
[M15]

Pros: Multi-feature solution especially being portable. Amazing clarity after burn-in. No problem with battery life with unbalanced and balanced mode. Can drive 300Ohm Headphones on 3.5mm just fine. Insane. Cons: Runs a bit warm with normal use. With DSD it runs a bit hot, nothing unsafe though. Side buttons are easy too press, just by holding it you may accidentally press an unwanted button. Good thing there is the hold switch. Other notes: I personally do not care with Android 7 but some people care. You are buying a top of the line music player, buy a tablet. Sound quality is better than Astell&Kern SP1000, falls just shy of Astell&Kern SP2000. Not related to hardware but FiiO App's Equalizer stops working from time to time. Currently being investigated as only solution is to factory reset firmware. Low-Pass filter is hard to notice unless you got some crazy source files. Be VERY careful of the 'OVER THE EAR HEADPHONE' mode as it increases the impedance and may cause your very sensitive IEM's to be blown. Worth it? Is it worth $2000? Depends. If you are looking for a DAP, USB-DAC, Bluetooth 5.0 Hub, 300Ohm Over-the-Ear Headphone driver, being able to be your Desktop and portable solution? Yes, aboslutely. To buy all those separately at a sound quality THIS good would exceed the cost of $2000. If you are looking to upgrade from a FiiO M11 Pro? After the burn in, sound are much clearer, larger sound stage, faster response times, overall huge improvement but being on the stingy side, the upgrade is hard to swallow unless you can sell your M11 Pro for a decent chunk of the M15's cost.
