you can double check your volume with alsamixer and alsactl store command. !!!! remove your earphone from E1DA and lower the volume on gnome volume bar before the next steps... 1 - run alsamixer command, press F6 and select E1DA from the list 2 - you need to change only the bar on the right...

I did on my unit some days ago, measured only (75ohms adapter from Dunu)... Didn't heard it with impedance adapter. Bass enough for me without.

I'm not very used to es100 to be honest, received some days ago. All my thoughts until now are based on a/b direct comparison with m11, volume matched with my minidsp umik-1. My 1st impressions of 2-3 days of use are very positive with es100 and my iems, so decided to do some more controlled a/b...

I think very close with a little bit advantages... with both of my iems es100 presented a little better tonal balance, instrument separation and more depth on stage. With Oriolus MK2, m11 sounds more mid centric, with less sub bass presence and more smooth treble. The mid-range sounds more...

Any thoughts on es100 sq vs iBasso dx160? I just received my es100, suberb sq compared to my m11. I'm just considering sell the m11 to try some other daps like dx160.

are the USB output enabled on the fiio app? On settings menu, chose USB output, enable it and select Native. This way works great for me with a chord mojo.

I'm experiencing exactly the same with Andromeda. No way R3 have 1 ohm (if i'm not wrong, it's what hiby stated) on HO Single Ended, balanced is even worse (for Adromeda's). I mainly use R3 as transport for Mojo, but at least the times I used it as DAP i really don't think it's warm sounding...

For mojo is better (more guaranteed) with mono 3.5mm pin like this one...

Hiby r3 Black 149 right now on Musicteck's eBay store and Amazon.

Thanks! My friend tried with his account, and same message appear. Very strange. 179 is a good deal yet.

I'm not able to apply coupom code on r3. :( Says I'm applied already, but I didn't.

hi @Reebonz . So, have you tried the recent new firmware with LDAC ? i'm very hope the bidirectional BT LDAC or APT-X works well as input to R3 + Mojo . Thank you!

Ama very good news @kenloveme ! but for the first launch (Nov as stated on kickstarter), Ap80 will support at least AAC on BT? For me is enough for now (i'm current using AAC throught BT on Fiio Q5 and can't hear any difference from APT-X). :L3000: Thank you!

I'm very interested on AP80 to use as transport for a Mojo and Q5, but i have a question: - can the AP80 receive audio signal via BT APT-X fom my phone (lg g6) and then out it to USB-c / Mojo ? I really want to know if bidirectional BT can work's that way... My mainly use will be offline files...

Yeah, make absolute sense for me. I hope Fiio just look at this little issue, even to show us what really happen to not connect with apt-x as default. I don't notice any major diff from AAC to Apt-x, though... but will be nice if we can just select the best option for G6. Good luck for us :L3000:
