I have a R30 with approximately 100hrs on it. I was originally planning on selling my Eversolo A8 and going the Eversolo Z10 & T8 combo but stumbled on the R30 and decided to try it with the intention of comparing it with a Z10. Well that never happened.
Even brand new out of the box I was impressed. I didn’t have a Z10 yet but did compare it with the A8. The R30 has a similar sound to the A8 in that it’s very detailed without sounding harsh and bright. Although similar, the R30 bested the A8 in fullness (weight ) and especially in sound staging both in depth and width.
Now I’m definitely not an expert and haven’t owned many $5k plus DACs so take this for what it is, this is the best sounding DAC I have ever heard in my system.
After one day with the R30, I decided not to buy the Z10 and I put my A8 up for sale. Would the Z10 sound better than the A8?, I’m guessing it would ( same chips - better power supply -isolation ) but the R30 just made me not want to deal with that A/B comparison.
I used the A8 as a streamer into the R30 via iis and USB. Both sounded excellent with the iis sounding better IMHO ( more openness in the music and wider soundstage ). The A8 has been sold and I’m currently using an Aurender N150 via USB ( of course ) and it simply sounds amazing. I did not do a direct A8 / N150 comparison as I did not have both units here at the same time. I plan on picking up a T8 soon and will definitely compare it with the N150.
I have only gone PCM so far too, so no comments on DSD and UpSampling yet.
Anyway, those are my thoughts. I believe you will not be disappointed in the sound of the R30. Now the remote and Streaming Platform is another story. ( I’m primary a Qobuz user )
