I am not sure if this is the best forum for the question best here goes.
I do most of my listening now at night in bed. Due to convenience my source is either an Iphone 5 or Ipad Air with premium Spotify on extreme setting.
I use a lightning adapter into a Pure i-20 and then into X-Cans V3 into HD650s, HD595 and SR80i (looking at getting closed cans as well).
Here's my question.....is there any point in upgrading my amp or dac? Can I squeeze better sound out of Spotify?
If I can would would be worth buying?
