to be clear I am not a hardcore audiophile, I do enjoy high fidelity sound but I don`t own much lossless audio more like high bitrate mp3s, and I do believe that at some point u get a low diminshing return for your money, I know that the x5 is a superior player overall, now there is an offer on amazon for the x3 + connections + 64gb micro sd for 200$ which is a bargain and the x5 is 400$ for some reason and not prices at 350$, anyway I will be using the player mostly outdoors and doing sports with a shure se310 and sennheiser CX685 adidas and sometimes using it with my denon ah-d5000, the reason I am asking this because spending 400$ on a portable player is kinda alot and
I want to know how much better the x5 actually is in terms of sound quality? for the headphones I have( I might upgrade to shure se5xx in the future) and the music I play ( mostly high bitrate mp3) I was considering the E18 DAC/AMP and pair it with my android phone but honestly I want an all in one player that is solely listening that I don`t have to connect and disconnect, which I will leave my headphones connected to all the time.
I am not limited to only these options I have seen the ibasso and I would welcome any opinions and suggestions.
I am really hesitant to buy the x3 because of the outdated UI. your suggestions are well appreciated.
