The limitation is more likely from its software OS, probably some sort of Linux.

SonyOS is also Unix and can handle at least 90.000 tracks

My views:

1. Non-android dap, linux based OS. Pure music playing. I do not even want Tidal on it.
2. I am okay with battery life of 10 hours as I really look for standby in non-android daps. A standby of 40 days is awesome feature to have. I really do not want to switch on and off my daps after a session of listening.
3. Size is just perfect. Small and compact.
4. I am mostly into iems, staying away from headphones. I just hope it pairs well with my iems and has enough power to drive most of them.

How good would it sound is the main question. If it sounds as good a DTR1, it will just be amazing. But I highly doubt that.

hard to compare r2r with delta sigm, all depends on your preference

Does anyone know whether it has native Hires audio recorder built into the Darwin OS? Will be great if I can use as USB dac and record at the same time with those 2 memory slots.

Just bought RU6 from a fellow headfier. If I like the R2R sound signature, I will also order the RS2. Otherwise, I may turn to DX170.

Just get a RS2 from a local shop, very handy little player, solid built. Comes with a leather case which is fitted tightly.

First Impression, kinda of Sony's tuning, warm, organic and musical, yet not that booming. Female vocals is quite addictive liked the older generation of AK DAP with very beautiful instrumental performance. The background is clean and dark, half of the volume (4.4 Low Gain) can drive my planar HOOK X well. The light at the side turns orange when playing lossless, and turns blue when playing hi-res.

I am so impressed on how good the RS2 sounds with its size. Its SQ is way better than the R5II ( I tried before ) to me. It's simply more refined than the DX170 I try the same time.

If bluetooth, wifi, streaming is not what you are concerned for a new DAP, then RS2 is good to go !

Sounds encouraging!! Have you got a chance to compare it with Cayin RU6, which is also built on R2R architecture?

I just realized Dethonray dtr1+ supports 160k tracks and is using an even worse CPU than the RS2 (jz4760b vs x1000e).
So 50k must be a limit set by Hiby for their OS, they could probably increase it without any issues. Not that I care, I don't even have 50k songs.

Does the bass has good quantity, but still good quality to prevent bleeding into mids?

That would depend more on the iems/headphones you are using.

The signature of r2r dacs in general are warmer, bassier, more analog presentation. Certain things like echo, reverb, decay that contribute to the euphonic effect are more apparent in the r2r dacs.

Its a big difference imo from the delta sigma dacs and if you have only heard DS dacs, it will take a little time to really notice the full difference. Its more easily noticeable when you listen to it for about a week then go back to the DS dac, I found that I did not enjoy the DS as much after experiencing the r2r dacs.

It’s probably a combination. The Sony A45 could only handle about 35.000 tracks while the A55, ZX300 and 1Z can handle my full library of over 60.000 tracks yet are essentially using the same OS
