Nah, that's not going to happen. Fiio aren't making the X1 just for a few head-fi guys that don't mind carrying an extra amp with their DAP. First of all, not everyone has an amp or is willing to buy one or always carry one and interconnects add additional buk also coz not everyone will be making or buying a custom low-profile ic. Second of all, the X1 is obviously supposed to be an all-in-one affordable DAP for people on a budget or just average consumers who want to get a taste of hi-res audio and better sq but aren't the type that will spend a lot of money on portable audio. And a requirement for a mandatory external amp suddenly will decrease X1's overall value as a small portable DAP and also scare away a lot of consumers coz no - removing the amp section won't make it 30 bucks cheaper.
Fiio obviously has a plan and target market for each of their DAPs and if you're an audiophile and don't mind bulkier size you should get an X3 or X5.
