chaps, IMHO this hobby is all about music and sound we want to hear from our gear... as such i see no problem jumping from iphone iems straight to 1p2 or similar calibre iem because there is no point in analysing sound signatures when you know what and how should sound for you. this journey is rather a pain we are taking to find something we like and what suits our wallets. i do not see big reason in buying all they way to the top when have enough money. upgrades are always done at a loss at least most of the times. however we all like to know about hidden gems like H200 or DN1000.
