oh you've got a hifiman hm901r interesting! can you compare the two?
901 with an iem or balance card is no worse than ar m2, it's just different, the disadvantage is the inconvenient software, and the advantage of Bluetooth ldac compatible is that I most often use it as a wireless dongle for streaming. ar m2 is more powerful and has an analog sound. 901 is multi-bit cirrus logic in terms of its sound, that is, it does not have an emphasis on any part of the range, and also has good attacks, while hifiman’s high range have a better sound, the scene is similar to ar

I assumed it would be a good combo. And it turned out to be true.

Please tell me what is the normal play time from the battery in the ar-m2?
I can't say what's "normal" but on the pair I've had for a little over a month I get about 5 hours of music from full charge.

So while I'm pretty good at certain things relating to audio, I recognize I'm a complete noob with certain other things. One of those is the line out from daps, as I've always been primarily a desktop system user, so forgive the extremely basic question.

If I wanted to use the ar-m2 as a source into a desktop amp is there anything in particular I would need to know? Could anyone recommend a cable? The plan would be to go from ar-m2 to ampandsound booster box to tube amp.

I’ve managed to find a used one off eBay. It’s not arrived yet. If I like it then I’ll send it to Steve from npaudio to get it modded and probably get the battery replaced. Can’t wait to try it 😀

Here are a couple pics from the only protective case I could find, the same on that people mentioned earlier in the thread, the one from a Chinese eBay seller. Dark green, with ‘AR-M2’ engraved on the back.

Show us the back, my friend. What's that engraving look like?

Here it is! I considered putting my name, but if I ever sell this I doubt someone is going to want my name on the case. Not that selling seems likely…
