I just wanted to say thank you to all who have contributed to this long thread - I have been thinking for several years about pulling the trigger on a DAP that can play my high-res files bit perfect, but I was always concerned about reliability. After spending several nights digging through this thread, I finally decided to get the DX90 - what a great product! I am loving it, especially with my V-Moda M-80 headphones. It took quite awhile to fill my 128 GB micro SD card, but now that I did, I have no problems with playing it. I also immediately put in the Lurker FW after taking it out of the box, which may be one of reasons, the unit seems to be working so well. I do have a couple of questions for you gurus here:
1) Most of my artist names come up "null." This is not such a big deal since I have organized all of the files in folders by artist, but I was just wondering why this happens. I am using aiff files that I have most tagged on iTunes. I have a feeling that it might be more hassle than it is worth to get the artist names to show up if I merely chose music through the directory function.
2) What are the best ways to deal with additional memory needs? Is it better to buy a few 128 GB cards and switch them out or to buy a large flash drive and hook it up through the USB? I see there are plenty of 256GB flash drives that are cheaper than 128gb cards. Is the usb for storage less reliable?
3) For home use, can I play the player while it is plugged in and using say a 2TB hard drive? It sounds like that is supposed to be possible, but I have yet to hear reviews of doing that.
Sorry if any of these questions are a bit newbie in nature and if they are covered elsewhere in this 500+ paged thread.
