I also settle down with LME49990. It has great resolution, treble and staging. The bass might need more weight, but it's ok with my IEM. Sometimes I think it is a little loose, but compared to the more "refined" yet "confined" sound of 627 or 797, this sounds more natural to me.

How do you install CWM recovery without touching the new 1.5.0 firmware you just installed?

Sure I understand and I have been using it ever since it was available to DX50.   In order to install RB we need CWM recovery. CWM is not a standalone installation. The link you sent me (which is the one we all get RB from) says get CWM from DOC2008's firmwire, an update.img file that has CWM...

  You mean reinstall the update.img from Firmware_DOC2008 for the CWM and then load RB.zip? That will bring it back to 1.2.8. Am I missing anything here?

I have no issue doing all these. The question is how to install RB after 1.5.0 is loaded.

Hi Olddude,   I didn't get it here. The CWM recovery we used before came with DOC2008's firmware (an update.img file based on 1.2.8). Once I come back to stock recovery and flash with stock 1.5.0, how can I install the CWM recovery again? My understanding is that we have to wait for DOC2008 to...

I'm also running Win 7 but I encountered the signature issue as well. The driver was installed but Windows would not let it work. I have to disable the driver signature enforcement to get the DAC to work. It's similar to Win 8; just press F8 when starting windows and the option is right there...

Hi, is there a way to have the stock 1.5.0 with Rockbox? If not, DOC2008's 1.5.0 based ones are also ok. It seems these don't come with CWM recovery.   How does the "ROCKBOX for FIRMWARES BASED on v. 1.5.0" work?         Quote:

I had a similar experience with OPA627 and AD797 as you and I don't really like their sound.   Today I just put in a pair of LME49710's (borrowed from another cheap diy amp) and I love them! I don't know much about opamps and I am not even sure if they fit this amp (I just checked the power...

In most cases I don't need a faster scrolling, except when I am setting freqency of a higher EQ band. I tried to set the scroll speed to max (17) and it did help some.

One more: the lag when you press any of the three buttons. This bothered me the most for some reason.   And I truely like the EQ. I've saved many EQ settings for different headphones/genres/modes. It is as convenient at using foobar now.   The power/back button still doesn't bring me to the...

It costed me about $350 for parts and materials, and three months to put them together and tune them up. The acrylic shell needs UV curing and might not be available for many. You can use some other materials instead and manually make a shell. Or you can start with silicone but then you have to...

Right click within the folder -> new -> text document. Then change its extension to .ini.

cooperpwc, I didn't do anything to that part and found it functions the same way as the original theme: 3x3 grid as you have known. All themes I've tried on DX50 work the same way. I think these touch functions are build into the firmware and is independent of custom themes. You may need to...

A little off topic but...   I started from sketch. The place I work happens to have all tools and equipments I need (this is very rare I know and I don't work for a CIEM company), and I am free to use whatever I need, so I thought maybe I can just make one pair by myself.   The shells are...

This is AluminArt. I like the tone that fits DX50 body color very well. I changed the font for album and artist to 13-epsy-asian.

My experience with RB ADB: we need to do three things:   1. Install ADB USB Driver     I tried two ways, both worked: ·        From SDK installation (you can download it here, make sure to pick the right version). After extracting it to a folder, run the “SDK Manager”, pick at least...

Finally I am satisfied with my portable rig: DX50+RB -> UHA-6SII -> DIY CIEM (5 driver/4-way!).  I like its sound even more than ODAC+O2+Mod Q701! Really enjoying RockBox now. Thanks for your work!    

You are always helpful...   I'd just add that you can use different fonts in the same theme or even on the same screen. For expample, on WPS page, I am using a smaller font for artists and album names and a bigger one for titles, just to save some space and make it look nicer. You need to make...

That simple?! Everything worked like a charm! I wasted a whole evening and half a day just to find this...   Now I have tons of themes and fonts to try out. I used GUN-unifont and Asian languages are not a problem any more. I even figured out the EQ presets: the default folder for "Browse EQ...

Thanks man, this one worked. Now there is still the driver issue. After installing the adb usb driver, DX50 is recoganized as an Anroid ADB Interface under "Samsung Adroid Phone" , but "ADB DEVICES" doesn't find any adb device. Tried many times, many ways, still the same. Need more time ...

Also, when I reboot the player, all playlists I made are gone. And EQ settings can never be saved on my DX50. This is on a fresh copy of RB. Wonder why only I have these weird issues...   However, I do think the RB sounds better than stock firmware. After switching back and forth many times, I...

This is frustrating. Whenever I try to run QtADB, my Windows 7 refuses to do it. I've tried two desktops: "QtADB has stopped working." I've installed SDK, located the adb binaries, and installed usb driver. I even copied the aapt.exe file to that folder. I couldn't even go to the step to connect...

I see. Will try.

I did that, but when I got back to playlist catalogue, there was nothing there.   I'll reinstall it later to see what's happening. Thanks
