Inside of QA360LE, wanted to find out what opamp is used for analog output, but the opamp has QA360 written on it instead of a model name from TI or AD. Well played QLS, a secret it remains.

Tell me about it. I haven't bought another dap since QA360LE, it cured me of the upgrade disease. I use the 1.4.05 firmware, with ciems, or digital out to NAD M51 and Hivi M3A.

The kind of setup you're using with the qa360LE are exactly what some of the audiophiles at mainland and hongkong are using as .
This player is good to be use with those full size setup , many of them pair it that way , and the result they say is damm good , The LO is damm good .

But I'm with portable setup and i heard quite a numbers of players in mainland pair this LE up with the venture electronics balanced amp with their earbuds with fantastic results , i follow suit and yes these are the sound i been searching for , the sound of my dreams .

I'm not good at finding the correct words to describe what I'm experiencing with them , how I wish you could listen what i had been listening to

Has anyone figured out a way to add a playlist to the ‘favorites’ folder? I’ve forgotten if this was covered or not. I have such a huge library and I have not been using my qa360 much just due to time it takes to scroll through everything!

Scroll to the song or the folder you want to add to the fav folder , then press and hold the middle button for 2 secs then let go will comes out with a Add to favorite Yes / No .

Thanks! I actually meant can you add an m3u or playlist file into that favorites folder... rather than adding each file using the favorites system inside qa360. But I don’t think that you can. Anyhow, thanks!

There's a saying power is nothing without control.

With the right pairing combination, you can easily drive even a cheapo $10+ earbud such as a Monk+ to heaven .
