The X3 in theory should work with any PC from XP onwards but it is much easier to buy or use a micro SD adapter. You can buy small adapters that plug directly into a USB port and your X3 memory card will be detected as a hard drive. Then just cut and paste your music files.

I gave given up plugging my X3 into my Windows 7 PC. Instead I take the micro SD card out and put it into an adapter which is read fine by my PC

With my replacement X3 I can see all my albums and I have about 58gb worth on one card. All of the cards I have work with this model. If you are still able to return it then I would and ask for a replacement. This is ONLY my opinion based on how I resolved my issues.

I have to agree with you that there are issues with most types of complex technology and that it is unreasonable not to expect the odd issue.   I would argue though that there are varying levels of what a consumer should expect based on the functions the gadget is expected to perform. For...

Technically the X3 is miles ahead of the iPod and other portable players I have tried in terms of quality of playback, I would not argue about that. Free software is available for a variety of functions but surely a buyer of a consumer product should not be expected to trawl the internet to find...

Hi James   With my X3 came a leaflet recommending I buy from HDTracks.com which I assume that because FIIO put it in the box, must be a recommended source of music. This is where I bought the Rod Stewart album that caused the problems. In the instructions that came with the X3 it does say...

The cards I tried in the first X3 I had all worked fine on my other devices too. I think one issue is that the X3 is very sensitive to any errors on a card, ones that other devices may work with.A format utility in the software would be the best solution. I also think that the format of the...

James   you are correct, the guys at Peachtree got back to me and said the same. They said that the 192/24 files play back via line out because the internal DAC in the Peachtree is being bypassed.    Now there is just the issue to sort out as to why the 96kHz files from the Rod Stewart...

Thank you James. I have contacted the manufacturer of my amplifier to see if they can help.  Once you have tested the 96kHz file that freezes my X3 I would like to know if it freezes your too. If it doesn't then it looks like I have a second faulty X3 :-(

Hi. The new card is a class 10 but some of my other cards are class 4 and they work fine. I only bought a class 10 in case it didn't work so I could use it with my camera where writing a 10meg image needs all the speed it can get. Have you tested your card? OK so take the card that is causing...

My new SD card works fine. It is a : Sandisk Ultra 64GB Class 10 Micro SD Card with SD Adapter - FFP bought from Amazon UK, a Red and grey card.

I have copied the 96kHz Rod Stewart files to a new 64gb card received from Amazon this morning but they still won't play, only the ones re-saved via Audacity work. The good news is that the card formatted and was read by the X3 without problem.   Sandisk Ultra 64GB Class 10 Micro SD Card...

James, just replied to your PM and am uploading 3 files to my Dropbox account. I have sent you the links but please leave it about another hour before attempting to download them. I hope they will help you work out what is happening. I am sending you:   1. One of the original 96kHz tracks...

There seems to be too many individual issues to know whether its worth returning or not. All I can say is that mine had major issues including a faulty coax adapter and I returned it to amazon based on that. I am finding even with the replacement that there are some issues which have not been...

Yep 192 :-) Thanks for the tip I will give it a try. I have tried re-encoding with JRiver and also saving them through Audacity but to no avail.   Update: Just tried it on one track and it made no difference. The 192kHz file will only play via headphones and line out and not via coax out.

I had very similar problems with the first X3 I received. I returned it to amazon and the replacement read the 64gb card that would not read in the first one. Another guy reviewing on amazon also had the same problems with regards to vanishing tracks. So far with my replacement X3 none of my...

After a day experimenting with my working X3 with 1.25 I am finding the following issues:   192kHz files will not play out of the Coax but will play from the line out and headphones, they will also play via JRiver Media Centre with the X3 docked and used as an external media drive.   I...

Replacement X3 Received ===================   Earlier today I received a replacement X3 from Amazon   1. The Coax Out works perfectly with my Amplifier resulting in a very impressive reproduction of my Studio Master collection, maybe just a tad bright but that maybe because I am...

Final Comment   After re-inserting the 8Gb card that was working fine earlier today and finding most of the files now not showing on that card either, ones that were playing OK this afternoon, I decided enough was enough and I have arranged for this unit to be returned to amazon as faulty...

Many thanks for the tip. I will give it a try this evening.   Update. I have made the file and listening to it through my mobile phone earphones I could clearly hear the hiss in the left ear which cut after the tone finished playing. Does this indicate that the small adapter is faulty? In...

As mentioned I have tried it in my Sony surround sound headphone set which has an optical input with which I use a coax to optical adapter to feed from my Blu-ray. Same problem, no sound. I have one last thing to try and that is feeding it into the optical input of the amplifier via the coax to...

OK so I have taken some photos but the Insert Image icon doesn't seem to do anything, perhaps I need to be a Triple Gold Ninja member to upload pics. Hopefully it will take this link to photobucket - http://s1120.photobucket.com/user/TrevorRowell/library/X3  (seems like you manually need to type...

The card is formatted as FAT32 using GUIFormat and is recognised by my PC as working OK. If I insert the card into the X3 it shows 0 however I can re-insert it into my Windows 7 PC and copy files from my hard drive to the card. The 8Gb card I am currently using was also formetted with GUIFormat...

Just received my X3 from Amazon today and apart from the fact I can't get it to read 64Gb cards the optical output does not seem to work. I am using the same cable connected to my Peachtree audio music box that works fine with other sources. The X3 does not appear to deliver any volume at all. 

Have the same problem but this didn't work for me. My PC recognizes the card has been formatted and I can copy and paste files to it without problems however as soon as I stick it in the X3 it reads as 0 Smaller capacity cards I have are working fine, it is only the 64Gb that won't work.  ...
