I bought it for around 90 $ from AliExpress, don't expect much more than 100 $. Mine just got in the country last week, I will share my experiences as soon as I can.

I cant compare, but I will try the BTA30 with my Sony WH-1000XM2 through optical cable plugged into my new expansion card connected to S/PDIF pins on motherboard, at the beginning of december.

Then it seems M6 does have one feature that BTA30 doesn't have.

And even LDAC format?

Thanks for the clarification. But then this may be a bit misleading on your website (M6 player): I am glad that I haven't order anything yet. Fortunately I just figured out that my motherboard supports S/PDIF audio, but only has headers, so I need this...

Good news for me. :D I just found out that my motherboard does support S/PDIF out, but it only has headers, so I need this: https://www.aliexpress.com/item/32961776637.html TL/DR: I will order this and the BTA30 on 11.11 sale to get them for christmas :)

What is missing from BTA30 that is in the M6 which makes that possible to transmit LDAC with USB input?

But the M6 does, right? What is its schematic diagram?

Yes, you got me. I see it now. No RCA Input, just Output. 🙁 It is only good if you use this as a receiver. Then it looks like this is really designed to be standalone. Yes I think I was wrong about M5 too as well, I wanted to say M6. 😅 I really wonder how can the M6 player transmit LDAC in USB...

What is the schematic diagram of M5 player if it can transmit LDAC in USB DAC mode, or it can't either?

It is a desktop DAC and amp. :wink: https://www.fiio.com/k5pro Edit: This Image:

Same. I am concerned about USB LDAC transmission only. I am glad that FiiO is trying to solve this, and actively responds to our feedbacks. Right now the only solution I see is to buy a K5 Pro to connect them together with provided RCA (like it is shown on one picture of BTA30) and connect the...

They replied me for the 2nd point with: "Yes you can USB input BTA30 and transmit Bluetooth signal, but LDAC format isn't included. Because there is a common technical challenge on LDAC waiting to solved." "And is it possible you can solve it and add that feature later with a firmware update?"...

I'm very glad, that finally I can buy it, however I wanted to use this for my computer with LDAC headphone and speaker, and I just saw this in the description: FiiO, what is the reason of this? No Windows support for LDAC? Could this be eliminated by a future firmware update? Please make a...

According to FiiOs feedback in a Facebook message, they are planning to release it next month.
