Been listening a little bit to my new R1 today.
Still burning it in though. So far, I'm happy.
I was a bit worried about highs being too sharp for me (I'm slightly treble-sensitive), but haven't had any issues at all so far.
I did with some of Bob's previous designs when he was at Trinity, but no such issues here
I started out with the black filters that were on the R1 when I received it.
Not bad, but I found the bass a bit too heavy, such that it unbalanced the overall signature a bit for my liking.
Again, this may change after burn-in etc.
Took a chance and put the blue filters in. Enjoyable! I'm getting a pretty big soundstage, decent separation, a good amount of detail but with a welcome dose of musicality.
Don't want to say too much or wax lyrical at this early stage, but am not regretting my purchase thus far!
Looking forward to A/B testing them against my iBasso IT03, which I have a lot of love for (see review in my signature for more lol)
