I spent quite a bit of time with R01 last night and it's definitely a highly transparent card, so far LPGT was my transparency king - unfortunately I don't have it anymore to actually A/B - but R01 probably is just as good and from memory (take that with a grain of salt) and I'd say R01 is more resolving. I was puzzled at how differently R01 portrays different recordings and I am not used to such disparity (midrange sounding full on one album, almost thin on another, powerful bass and then much less so...). Of course there usually are differences but with R01 everything has more magnitude and jumps at you. I was almost doubting what I heard but I switched over from album to another quickly and it was pretty obvious that R01 was not inconsistent, recordings were. It's much much less apparent with my M8, DX300 and R6 2020. I remember this about LPGT, but honestly not to that extent.
Also, there is something very special about R01 IMHO, notes pop and fade so fast from bass to treble where transients are something special (especially true of every EST powered treble in my collection from Volt to Spark to Elysium)... speed is overall something to behold... actually reminiscent of my time with the KSE1500 when I owned it. R01 is so clean and articulate, it brings every IEM I own to a higher level there. On a side note, I was dubious it could drive the notoriously hard to drive Elysium properly with 430mW@32ohms but it does quite a good job actually.
Last but not least I find R01 to be quite accurate tonally, instruments sound spot on to my ears, there is no coloration and instruments timbre is really lifelike.
I must say, R01 is more resolving and reference than I expected it's a highly detailed, very transparent and open sounding card. It does all this with great musicality... enjoying the burn in and expecting things to nicely change over time. Already midrange is a bit fuller overall were bass and treble were a bit emphasized initially.
