I have strongly considered the DX100. The two things holding me up are:
1. They chose to use an sdhc instead of an xc slot. I know that I can reformat cards, but fat32 isn't good for a large file system, and it voids your warranty if you have problems with it.
2. It's not going to Jelly Bean (or at least ICS). I realize that is beyond the control of iBasso, largely, given the chipset that they had to buy at the volume they would be making the device, but Android 4.X is just head and shoulders better than 2.X.
What I am looking for is a nice portable design (design wise, the iRiver AK100 hits the mark for me), a good 24 or 32-bit DAC (which the 901, DX100, and AK100 all hit the mark on) lots of available storage space with room to grow (the 901 is best here, since it supports sdxc, the AK100 is close with its dual slots combined with its 32GB on board) and a great, amplifier with low output impedance (this is where the AK100 falls on its face, the 901 will probably as well, and the DX100 shines).
I want these things so that I have a good portable to pair with the UM Merlins I am going to most likely order in the new year. I guess I can wait to see what the Pogo thing is like. Hisound has just never appealed to me. My Clip+ will do alright while I ponder my choices.
True enough. But the firmware on the DX100 isn't as bad as it's being made out to be. Plus you can root it and make it run smoother which I've done. I've made it minimalist. I don't find android as the OS to be a plus at all. In fact until the unit can use other players in 24/192 there really is no point in using android. I only see the main point of using this player is to play music so I could give a rip about android support on it. Also you have a point with converting the card to FAT32 but I did it and there are no issues. You could always convert the card back over if you noticed issues before it completely died. Also if the card completely dies who is to say Sandisk can revive it to even see if you put it in FAT32 lol. Pretty much when memory chips burn out they are unrecoverable period. So I wouldn't worry so much about it and Sandisk has a very high track record for quality. I have yet to have a Sandisk card go bad on me out of the years I've owned them. Plus at $40.00 a 60 GB Micro SD card is it that big of a deal? I just wouldn't waste money on the iRiver due to the 22 Ohm output impedance. That is not acceptable at all for a player that is suppose to cater to Sensitive IEMs. Pretty much the product is a joke in my book.
