Thanks! - Not yet, but I will try it, however I am still at 3.99V. I forgot to tell that most of the impressions were on SPDIF input on the DI20. I am very close to decide for DI24(non-HE) as I think the DI20HE is perfect for R1N. DI20 and R8 is still the best pairing.Nice to follow your tryouts with the different firmware versions. Did you also try the original 3.32 version? In my system, this is still the best sounding.. In serial mode.. most natural sounding, authentic with impact and weight in base and a no harshness i high frequencies.. (I have the nonHE version).
When I adapt to really listen to both DACs the R8H2 has some skills that are worth the experience. The timing/rythm, length of notes. It is now very distinct in the sound signature with the DI20. This has something to do with the DI20HE locking/influencing the sonic character for both. They are really close to each other on DI20HE, but DI20 is just better and brings out the dimension right in the mid section of the headpones(with R8H2)
....but I still feel R8H2 potential needs to be tested.
R1N is the sweetness when it comes to playing the bass
R8H2 is just levelled perfectly for the listener to tap into the layers and notes.
Both are equally at the same level of my preference.
