Oppo have just updated their IOS Oppo HA-1 Bluetooth Control app and made it IOS 11 compatible. The update is available in the IOS app store now.

Just a heads up to anyone who uses the IOS Oppo HA-1 Bluetooth Control app, in case you are not aware this is a 32 bit app. Apple will be releasing IOS11 tomorrow and no 32 bit app will run on IOS 11. If you do upgrade to IOS 11 you will not be able to run this, I am not sure if anyone has...

The Oppo UK site for this (https://www.oppodigital.co.uk/Accessories_info_36.html) has a picture of the remote up and it seems to look exactly like the HA-1 remote (which is a good and bad thing, I hope it is different enough to distinguish between them for anyone who has bought both).

Oppo have confirmed that they are selling a remote control for the Sonica (see below)

Not sure if this is a mistake, but in the What Hi-Fi review (https://www.whathifi.com/oppo/sonica-dac/review), they mention that there is an optional remote control for the Sonica. I have never heard of this, but if it is true, it would sway me to purchase the Sonica. For me, not having a remote...

Short answer: Yes (I use mine with an Oppo HA-1). I got mine from Amazon UK so its worth checking around for the best price.

Oppo have put up the UK pricing for the Sonica at £799 which translates to $993. This is quite a big mark-up.

I got my headphones yesterday, mine came with a Jupiter black spot. As I don't normally purchase wooden cups headphone, I have a question for anyone who does, do you think this black knot is acceptable? This doesn't appear on the other cup and the surface is smooth around it.   Thanks  ...

Looks like they have started selling the Sonica DAC from the main OPPO US website. I got my invitation to pre-order it just now.   Its a shame that I am in the UK and couldn't put the order in. I bought the Denon AH-D7200 Over-Ear Headphones instead :)

I found the answer to this was to reboot the Mac Pro (i too am running Sierra), whilst the Jot was connected via USB and this then allowed the correct settings to appear (after the reboot). Worth a try..   Michael

Strange, on my Jot, the maximum settings I can use (in the Audio Devices section) is 2 channels, 32 bit integer, 48.0 kHz

Your welcome, I am glad it was of use to you.

This location was given to me by Oppo Digital UK support so its not just for Mother Russia :)   Cheers   Michael

Yes, the firmware has been updated and is available here (http://oppodownloads.s3.amazonaws.com/HA-1_1.4.3.rar).   Cheers   Michael
