Hey, i have modded the Sr001 mk2 and i am quite happy with it. The output capacitors have huge impact on the sound, so try to find the Vishay ones if you want to stay portable. I am powering the amp with single 14500 Li-ion battery or with wall power supply (a good one)

This dock is pure digital. If you want analog output (RCA), than you need a DAC. I think it is better to buy the other DK1 dock with analog out.

I have managed to register it.

I am using Neutron and it works fine.

Thanks. I have done just that :)

How did you activated the Developer mode?

What do you mean by "IP address (which is extremely long but listed as several lines)? It should be something like 192.168.0.5

.

Maybe your unit is faulty. I am using the balanced output with Sens HD660s and it sounds great. The OS is sluggish, but it works. I have no issues with spotify, tidal, amazon music HD and the sound is great. Another question. What headphones are you using with the bal output?

On the M9 Fiio app you have Fiio link in settings. You have to put the same IP on the iphone app and it will connect It does not work with bluetooth on iphone, only wifi

It works, but only with the stock fiio player

If Amazon HD wont play and you just get a rotating thing (processing, processing) you need to start a track that's 24/96 in another app (i use neutron) then stop it and switch to Amazon HD and it will play just fine. It is some bug in Amazon HD app that wont activate the sound driver the proper way.

Just load your music on the SD card with a card reader. Fast and easy.

Sorry, i was not answering your post. I had hard time finding the output capacitors for the mod, so i posted a good one from Vishay that is actually in production. You can check Mouser. They have several brands and types of 2.2uf 350-400v.
