There seems to be a lot of nitpicking re this player of late so I thought I might jump in;
Have had mine for 48 hours. Formatted the card in the player as suggested. Fixed all my tags (flac) and album art with mp3tag as suggested.
I have not updated the firmware as yet, shipped with 1.20.
X5 paired with NAD HP50 @ 65% volume, no EQ = synergy. Absolutely f*&%king brilliant!!
I also purchased the E12 but will not need it. However, I will more than likely justify the purchase of the amp with perhaps another purchase ie, V-Moda M100's as I can see myself enjoying those cans as well for certain genres (damn you Tyler!!).
Like most of us I did not read the manual and within 60 seconds had the controls down pat. I find them quite intuitive. I have experienced no issues whatsoever. Certainly none of the issues mentioned.
Now as for the SQ which is what we should be concentrating on refer line 4!!
I cannot believe the the SQ I now have and I am absolutely no s*&t, hands down, stoked. Thank you Fiio!!
Like you ( now that I finally got my X5 unit in KSA-- not much love for audiophile purity in the area that I've seen thus far) I'm not seeing areas where I can complain much at all. I have the NAD's as well and sound excellent. Albert King sounds fresh and new again compared to my other Mp3 player but I listen to a wide variety of genre be it classical or pop/rock etc. I have the E12 ordered as well and similar thoughts on the possibility of it sitting more than in use. Though I may likely use it on the plane going back and forth to the US more. I went ahead and updated to fw 2.0 soon as I got it. It just seemed like the proper thing to do. Listening to it as a DAC through my 901's and a Miller & Kreisel sub made the compound a more pleasant place to relax in. I even lost track of prayer time here when I sit in my Big " Maxell" comfy chair. I was about to purchase the Sony HAP-S1 for ease of use and more room for files but I think the X5 has put that on temporary hold for a while. The A&K 240 may have a more intuitive UI to work with but the X5 is not shabby at all for the end user. Thank you FiiO for an excellent line of products And to the nitpickers I thank you very much as well ..without you this unit wouldn't have improved on its superior performance and UI tweaks.
