With new one, Fiio now has 5 different m11 daps… They could try made “m11 pure” based on ESS. No android, no streaming, no BT, only pure delta sigma music experience

I'm waiting to see which DAP manufacturer (if any) is first to use the AKM 2 chip solution. AK4191 with the new AK4499EX.

Hum. I'm no expert. Would it be hard to implement? Sounds interesting enough, actually.

Me too. Also, ESS9039MPRO ('M' stands for MQA support)

If this is the case, we are looking at $2k+ flagship DAP, probably also quite bulky.

In the photo, I counted the HiBy RS2 (for each of the two stereo channels) 20 pairs of resistors in a row + 3*4 more =12 pairs of resistors below (next to the chips) = total 20+12=32 pairs of resistors of the R-2R matrix per channel. It turns out that the player is really 32-bit, but the question arises - how does it reproduce a 1-bit DSD? By converting to 32-bit PCM?

The RS6 has a separate dedicated 1-bit DSD processor that natively handles DSD files before sending them to the amplification stage for output. I believe RS2 is doing the same. Therefore, if your library consisted of primarily DSD, RS2 is not your choice.

Are there any reviews out yet? My searching turns up nothing other than announcement/promo stuff.

There are two reviews in Chinese on some Chinese forum. However, I usually don't trust those early "reviews":

Thanks. I agree with you regarding trusting the reviews. They are hard enough to read let alone anything else. But it keeps the appetite wet.
I have a feeling I'm going to end up buying this thing before any tangible reviews come out anyway.

I should receive my RS2 in a day or two. I will then do a comparison with the other R2R device Cayin RU6 that I own. Stay tuned.

where did you order? website says theyll ship around september

I read somewhere that it was virtually impossible to get more than 20 bit resolution with pure r2r ladders. The tolerances and changes against temperature that would have to be achieved are virtually impossible. I think it's a 20 bit ladder, and the other resistors near the switch chips are supportive of those chips, not the ladder. The rest of the resolution is achieved with the support of FPGA chips. I have found this video, in which it is explained quite well, starting at 5:15. I once read an article where they explained it even better, but I can't find it.

Same here. Looking forward to receiving mine in the next few days as well. This will be my 1st R2R based unit, so no point of comparison for me.
