SBAF'ers... I'm thinking about a portable hi-res player, but I'm clueless about important things of which I need to be aware. I started doing some research, and I found this Sony player on amazon: Sony NWZX300/S. It seems to check all the boxes: DSD and PCM compatible, sturdy aluminum construction, balanced connection as an option (just in case I actually get a pair of 'phones with that connection...), expandable storage (micro sdxc compatible), LDAC for bluetooth (not even sure my Bose does this, but I may pick up a pair with LDAC once I do more research...), etc. Is this a good DAP for the money (around $700)? What are similar, reputable alternatives in the same price range? It would be nice to relieve my iPhone of portable music duties - I primarily listen to block out noise at work, and sometimes before bedtime to block out the noise at home. Thanks.
