Very late to the party since it's now 2019— I finally decided to try some modded FW's on my trusty DX100... Sure the UI feels smoother with the Fidelizer Audio "Purist ROM" version, but the SQ is a major downgrade to me. Sounds less musical, harsher, brighter in the high range, and boomier...

No ø6.5mm headphone output on that single ended amp module, shame:disappointed:...

My Thanko Silent Mouse EX finally gave up the ghost after over half a dozen years of duty, so I went looking for current silent mouse offerings, and am currently trying the Buffallo Premium Fit; while apparently better built, it's not quite as silent, but will do until I find a better option...

I meant that's how I found it : I typed HDP-R10, and found the Ray-Out case like that.

You could try typing HDP-R10 in eBay for example.

Awesome! I might order a new one when I give into "upgrading" my old DX100, giving the DOC2008 FW a try, and also the Ray-Out case: see how that one works versus my Norêve one.   As the new DX200 is out of my reach for the present time and near future, I might as well treat myself to some...

Tasted yesterday some Coteaux du Languedoc 1996, Domaine Peyre Rose, Clos Syrah Leone. Amazing.  

Yes, well, iBasso also denied that there was any SQ or sound signature differences between the different official FW releases for the DX100, but nearly all of the DX100 users agreed there was.

Desktop DAC and 6V output at disposal and you expect long playtime with high-res' & DSD? Honestly...

I'm just warning iBasso, maybe a bit heavy-handedly, that everything will have to be ironed out before I consider a new DAP investment. I'm pretty sure I'm not the only DX100 owner with this mind-frame.

What's the point of a "pure" mode that can't be used? But fair enough, let's wait and see. Time will tell.

I don't know. The DX100 software never got stable enough. Only those talented third party FW programmers saved it. For $830, that's not so great. Now five years later and $869, it seems to be starting off the same way. The hardware is top notch, maybe best in class, since some say it gives the...

And there I was hoping that they'd released a more stable OS  with the DAP from start, but no... A bit sad that it'll be a third party modder who will get it right and not iBasso themselves. They should hire that Russian chap who releases many fixed FWs.

N.B. I've just created an entry in the DAP section of head gear for the DX200, so people can post their reviews there.
