    wow, cannot believe I have not even been aware of new Etys SR-XR. Good on them for developing these legends further. I personally did not expect this, and am glad to see they have not gone down the route of multi drivers etc but rather refine an already superb product.(with options)   ...

     I am on True Sound V1 and with Gapless turned on, there are indeed issues with rebooting. Never use DX50 with Gapless turned on usually but something needs fixing here. With Gapless turned off it works fine.

    are you talking about: Dx50 TRUE SOUND BY DOC2008? This is based off V2.3.0 DX90 firmware (shows D50 firmware 1.9.2 on system info). from Doc's thread: There is a version 2 of this with slightly more warmth (which I am currently testing (on modded D50) update: back on Version One for now...

    got round to doing the extra caps mod, (already done Panasonic FC 220uF 10V) pretty happy with my DX50!   Thanks Coil, Panasonics are a worthy upgrade.   Only heart stopping moment was the yellow screen when I booted up!..............turned out I had not pushed the display ribbon back in...

    Hi Coil Good shared info, great. Have decided to solder in 6TPE100MPB (3528 case) rather than the 6TPE100MI (7343 case) the main difference being 25mΩ vs 18mΩ, after some reading I concluded that there will be no apparent difference in audio quality between the two (but hey, you can sleep...

    so you managed to get the large caps in.....well done. Was there any extra soldering considerations in fitting these?   Great job Coil.

        HI there   I have replaced the heaphone socket on my DX-50. It is a pretty straightforward soldering job with the PCB removed. You can ask Ibasso to send you replacement Headphone socket, they are pretty cool regarding customer service in my experience.   If you  are not confident...

    Regarding change of Dual Differential Amplifier I think this might be a worthy upgrade: JRC: MUSES8820E http://uk.mouser.com/ProductDetail/NJR/MUSES8820E/?qs=sGAEpiMZZMtxdzBvM0rKcdcB8W9ucxBQ8hRkSqFfJ7c%3d maybe it is not suitable though to be positioned in the circuit straight after the DAC...

    and you were absolutely right .........but you already know that:-)   I incorrectly used the Right Mark Audio analyzer and used a generated swept tone produced by wavelab, this was not going to bring anything accurate!   Could not leave this undone as I wanted to at least do a correct test...

      Thanks, will give that a read.   Not a terribly scientific approach I admit:-) (not tried this before)   I volume matched the outputs at each gain setting and recorded the signal on each at 32bit float and 48 Khz.   No, the 'scale' type is linear and the first one Logarithmic on...

     I realise this, just added it in without thinking.   Regarding the gain settings and frequency. I did a quick initial test into RME recording equipment for all 3 gain settings.   Update:   test results removed due to being completely incorrect!

        not sure about this:-) Running 100 Ohm ER-4s  IEMs on high gain (with DX-50 Capacitor upgrade) and  my chosen Doc firmware I cannot agree with this statement.   Cheers

    So a short while back I found the Dunu 75ohm adapter as a direct alternative to my ER-4pt to ER-4s adapter (which very occasionally causes dropouts when cable is bent near plug end)   So it has just turned up in the post........   Did a careful A B test for differences and suprisingly the...

        Come on Coil, everyone knows none of these firmwares make a night and day difference, it's all subtle preference depending on everyones hearing and headphones/iems. If he feels that a firmware works well with his cans and feels it is much improved......then that's fine.

      As coil said, try out some custom firmwares they really do make a difference.  Sound Unlocked and Docs Favourite Final  Ultimate if you are on Lossless only. If you are still wanting to squeeze more out of the dx-50 then see the MODS thread.   The Volume peaks were an unfortunate part of...

    HI   Think my Er-4p to ER4s adpater is on the way out (only use my Etys as ER-4s), get dropouts every now and then when walking around and the adapter is the culprit. I could canabalise it and make some modifications like replacing the female socket and shortening the adapter cable.......but...

    Thanks to Babs for your guides and to Coil for the capacitor recomendation.   Successful upgrade of capcitors to Panasonic and a nice subtle improvement, there is indeed a removing of a slight veil. Something beyond what firmwares can acheive.   I took out the whole PCB as this is really the...

    Odered direct from Ibasso. I doubt they would want to get into the habit of supplying these though as they would understandibly want to handle 'repairs' etc themselves?
