I won't call myself a Audiophile in any sense, but I do enjoy having a dedicated audio player with high resolution audio and good quality software/hardware. I'm currently rocking a NW-A26HN Walkman that I want to upgrade. I have the biggest SD Card it can support and I've basically ran out of possible space (32GB model with a 126GB micro SD card in it). I'm bit of a Sony fanboy so I've owned Walkmans as my go to DAP for years now and I'm leaning towards the NW-A55, as it is coming to the US pretty soon only I don't know if it's a significant enough upgrade. I'm generally trying to keep the budget sub $300, a lot of my library is NOT high-resolution FLACs, I'm slowly replacing a lot of it for high-resolution audio. The Sony WH-1000XM3 is my current headphones that I literally just bought, so that's the type of drivers I will be using for the long future. I'm open to trying Fiio or Pioneer DAP or anything else but again, I'm trying to upgrade but I want the best bang for my buck. Any suggestions from my Audophiles?
