Hi Cooler fam’!
Last weekend I had the privilege to demo one more time what appears to be the most expensive single DD iems currently on the market! The Rosenkranz Silver HB Ruthenium which retails for $6500 (it’s the first time I actually try this one) and the Rosenkranz Silver KA 18k Gold which is a fat $8500!
These are sold monitors only, so no cable, ear tips or any other accessories.
These are not for demo in the shop but a customer from this store who recently purchased both of them as well as a special version of the Yatono cable (it appears to be a prototype) was kind enough to let me try his goodies, big thanks to him!!
The bank account wrecking trio :
The silver HB Ruthenium :
I love the look of these! So beautiful in black! My favorite. The pictures don’t do them justice! This set is actually the last ruthenium (black) made. It’s now only available for purchase in Rhodium (silver color), 18k Gold or Rose Gold.
Here is the Silver KA (the $8500 one), only available in Rhodium and 18k Gold :
It’s not very clear on the pictures but they are mostly matte with a mirror polished frame around the faceplate. Really cool!
Build quality is top notch and for the price it’d better be, right?!!!
Those sets are a bit hefty but not bad. They’re also very small in today’s TOTL standards.
Now, into the sound :
Well, the first words that came to my mind when I pressed Play were “OMG!!! What is that bass!!!

“. I mean, I knew already the bass was nuts on these when I demoed them back in February, but it still shook me on first listen, and I came to the shop preparing my ears listening to Anni 2023, which is already an IEM with a substantially meaty bass! That definitely wasn’t enough!!

These 2 bad boys definitely know how to put a smile on your face!!
I wouldn’t really say that the bass is strong… no… it’s more like the bass is lethal on these things!! It’s brutal, savage, fat, weighty yet it’s not sloppy or slow! It’s well defined with excellent attack and speed. It does bleed into the lower mids just enough to give that warmth and authority in that region without muddying things out. The bass quantity can get borderline overkill on some tracks but never really got to that point (for me).
The most remarkable thing about the bass is how low and deep it can go into the frequency spectrum! I don’t think there are many sets that do what these pull off! At least, from the iems I’ve heard, I can’t remember any other set that gave me that same impression! None of XE6, Rn6, Trifecta or Z1r did. Maybe EVO could be the only one that could get close, but it’s been many months I’ve heard it so I don’t want to draw conclusions on them. Also, some other challengers I didn’t demo yet like the FatFreq lineup and Singularity could maybe match these? I don’t know.
All I know is they do extreme sub bass on tracks like Solar Sailer from Daft Punk and Kill Jill from Big Boi like true bosses! Most other IEMs just have the bass loosing intensity and rumble on those deepest frequencies. Those 2 also loose a bit of linearity down low, it surely won’t hold as well as a true home system subwoofer but so far that’s the closest I’ve heard from that experience in an in ear form.
For the sake of making it easier on me, I’ll call them Ruth (the black one) and Goldie (yeah… you probably figured which one it is…)
Both feature the same bombastic bass, warm, lush, analog and meaty mids as well as good presence and detail in the treble.
The main difference is Ruth being a bit more balanced with a bit more presence in the mid / treble section, making it airier and a bit more detailed overall. Goldie pushes the warmth and lushness a bit further.
To try making it easier for you guys to imagine how this duo sounds like, I would say that they do sound like a mix between Evo, Trifecta and Xe6 without what I would consider their drawbacks. You take Xe6 warmth, tone it down a bit, add trifecta’s retro analog vibes and huge soundstage and spice it up with a pinch of Evo’s sub bass. You then remove Evo’s upper mids harshness as well as Trifecta’s upper range roller coaster response and that shouldn’t be too far off.
Needless to say I’m an absolute fan! And that since my first demo of Goldie! In the end I’m liking Ruth a tiny bit more and fortunately they are a bit cheaper but still stupid expensive…

It’s absolutely not worth that kind of money, but I’m selling LP6 Gold and Ragnar to fund these! I guess that’s a clear sign I’m really in love with Ruth!!

(and also totally nuts…)
@drftr there you go pal! You’ve got my impressions!!

But please don’t blind buy this based on my impressions (or anyone else)!!! I would feel so bad if you don’t like them! They’re really special so it’s definitely not for everyone! I decline all responsibility if you don’t like them!! I’m ok to take credit if you do like them though!!
Cheers guys
Julien
Edit: I forgot the Yatono!! To sum it up, it sounds great but worst ergonomics ever!! lol
