I had problems with one of these cards some months ago - there were some duff ones about. I returned it and the replacement worked fine. If you have a windows PC try h2testw.exe, a free programme. It will take time on a card of this size but will tell you if the card has any problems. I have a...

It is the one with the 65mm ribbon. I got it from mfactors.com in the USA - prompt delivery and really good service for a total cost of $30.   http://www.mfactors.com/kz-b19-065-sd-to-micro-sd-fpc-extender/

Yes, minor bump. But happy with the case keeping the adaptor in place and covering it.         Doesn't effect anything I want to do with the player - I have tried it both solo and with the amp [however only did the mod yesterday].

The weather has been a bit bad here in the UK, so finding myself prefering to stay indoors I thought I'd try a little maths [ based on what others have posted on here].   So take   Then add And this equals         with a residual of a certain amount of smugness.   More...

Liking 1.2.8 both with and without amp - Thanks iBasso.   No dsd files in my collection, so searched for free one on the net and found http://oppodigital.com/hra/dsd-by-davidelias.aspx   Just in case you also want to try this format. Very mb hungry though!

I have purchased many items from amp3 over the years and been very happy with them. I have never seen such a bad advert as this, not just the photo but the text has fonts listed as well. Please don't take this as an indication of their worth as suppliers.

Let me be plain - I disliked 1.2.7 and removed it from my player. I had no problem with 1.2.6 at all. having a few quid in my pocket I decided to invest this money in an external amp. I connected it and found an immediate improvement in the sound I was hearing. I then re-installed 1.2.7 and...

Until 1.2.6 I was happy with DX50 and no amp. With the arrival of 1.2.7 I had an intense dislike of the sound. I looked in the for sale area of this very oracle and purchased a second hand amp. By using the line out to amp route, I now find the sound to be constant no matter which firmware is...

I was vary happy with my DX50 and various headphones, but adding an amp took my listening to a whole new level, with all of the headphones I have tried. Not had any v3 - but why not give an amp a try and let us know?

Always worth checking the card - I had a duff one [Sandisk ultra 64gb] which formatted OK and worked fine on a colorfly C3 but caused problems on my DX50. I use h2testw on a windows PC to test my cards.

Yes it is, tried it and immediately re-connected the c5 again - damn it, I'm hooked

Third day as owner of a c5 - using it as much as possible. Clear, well defined signal from it, wide soundstage. Was very happy with the HO from the DX50 until I got the c5, now I'm not sure I will ever go back. Not gotten into the whole cable issue yet, but there are some interesting posts on...

I had 'card problems' with one of my sandisk 64gb cards. I used h2testw.exe [ on windows ] to test the card, and found that it was the card which was faulty, nothing to do with the DX50. My other 64gb sandisk has performed perfectly since I've had my DX50. So, not wishing to teach granny any egg...
