Greetings from Sweden,
Long time lurker, never posted here but this time I felt I had to...
Just got my RR1's s/n 55 and my initial impressions are - pretty spectacular, (sub)bass is awesome and the FR is really nice, like a HD-6XX with more and better grain free top end and estat speed. Can't compare with Omegas as I have not heard any yet, but I would say altogether better than ESP95X / L500 and different flavour to L700 Mk II - not necessarily better nor worse . Anyways, take these initial impressions with a grain of salt as, well, they are initial. Listening through a 353x. A KGSSHV is on it's way from Mjolnir though
Mine is no.54.
Dap Sp1000ss
Balance xlr3 silver
Amp Srm 007tA
At the first unbox moment (w/o xlr3 cable. Cable was rca copper).
I though: Huh? Something wrong with Headfiers. They said, they posted this is dark side headphone!
I love this sound, balance tonal toward bright side abit as like my hd800s.
But just 1hour later.
I agree. yes! dark.
Big change happend quickly to same as I read on this thread.
When writing this words, I've just done 1st FR test by hearing.
Tone gennerator app @ Sp1000 -> xlr3 ->007tA ->RR1 ->my ears.
I must say too much distortion on range of 20-60Hz.
I never ever facing this on my headphones before.
Volume is 50% on the amp with 2.5V input. That is not quite big spl.
Any combine of two tones at 20-50Hz also make the same distortion.
But combine with higher tone such as 300Hz, distortion disappear.
So I am fine, I listen daily and have not facing this problem.
STRANGE THING!!!!
After tone test above ( total time about 5 minutes), RR1 brings me a very good sound!!!
My brain does not need to readjust when switching between hd800s and RR1 (except huge soundstage of 800s).
I read on manual there is guidance for solving the case the film stick on metal mesh. That is not my case, but 50Hz sine tone said to be used.
Is there a best way to burn in a headphone other than playing a list of songs?
Is sine sweep better?
Idk but Im thinking sine sweep and low Hz pure tone improved or solved an unkown "problem"
