Here is a Battery...

I am using a 1TB Sandisk Ultra with around 27,000 songs and have not noticed any slow down or other problems.

I use a Creative BT-W4, which works flawlessl. The only thing is that you have to use another device to pair your headphones. I could not get it to pair while connected to the RS2.

Yes, mine does not stay on the high setting either.

Yes, you are correct. I bought mine for $200 on black Friday. Currently the card is too expensive.

Yes, that is the one i use. Don't think there are any other ones available yet.

I am using a 1TB Micro SD card without any problems.

At least you know it will get there with DHL. I would not trust the Postal Service (at least not the Canadian one) with an expensive item like that.

I had the same problem. I created a folder called Music on the SD card and copied the album folders directly from the Itunes library manually. After that the DX220 scanned all my files under Android. The strange thing is that Dapper works with all my other DAPs but not with the IBasso.

Its available on the iBasso website. Just bought one, took only a few days to get to Canada.
