Koetsu surprise

I have to hand it to my wife.  Like many of us, I have always plotted and schemed my own system upgrades based on my interests and perceived best bang for the buck.  I have been concentrating on the analog front end for the past 4 years and have been listening to a lot more music.  I had been enjoying a Lyra Delos for its detail and upper register energy, a SoundSmith Zephyr Star for its amazing instrumental separation and full frequency balance and an Ortofon MC A90, that I purchased used of Agon.  Thought I was done with cartridges for a long time.
So when on the eve of our 20th wedding anniversary I received a little square box from her, I had no clue that she would gift me something for the stereo.  But there in front of me is a pretty little Koetsu Rosewood Signature Platinum!  
Its hard to describe the disbelief.  I had never considered a Koetsu.  My impression of them was that they were rolled off, romantic, old school cartridges that had been bettered long ago by the likes of Ortofon, Lyra and SoundSmith.  Never really read up on their cartridges given that their cheapest models were about as much as I would ever consider spending.  
Fast forward one month and I have put about 40 hours on the RSP.  From the first needle drop I was very impressed with the midrange presence and the utter ease and extension into the very highest frequencies. The bass did sound a little soft in the first several hours but has tightened up considerably.  It sounded its best loaded with 100 Ohms and mounted on my Mørch DP-6 with heavy brass headshell screws from SoundSmith.  I currently have it on my Jelco 750D with a Jelco Rosewood headshell.  
I don't think any of these arms are the best match but the RSP does sound quite special on all of them.  Just purchased a 40 year old Fidelity Research FR-64S.  Can't wait to listen to the RSP on this arm.  Any recommendations on the FR-64S/RSP combo are welcome.

This whole experience has taught me an interesting lesson about assumptions in our little hobby.  You just have to listen before you judge.  This is a quantum leap in musical enjoyment that would never have happened if left to my own devices. Anyone else have this type of experience?  First time you heard something that changed your mind about what you thought you knew about audio?

I married up!

That's the thing.  I'm enjoying the music more with the Koetsu. The A90 is fantastic too, does everything right but the Koetsu is informative. Have you guys listened to Herbie Hancock's Headhunter's Analog Productions release?  Those bass lines kill me!

Hey Karl when I cut you the arm board for the FR I’ll put an on the fly spindle to pivot adjustment on it. Well get that beautiful cart dialed in perfect!

What a lovely lady you have there Karl and a fantastic cartridge.

Unashamedly have been a Koetsu fan for 37 years and have had the opportunity to listen to many cartridges in my system along with a few of the Koetsu models since the original MC1 wood. I spent a lot of time with the RS, Koetsu Urushi Wajima, Onyx and Onyx Platinum. The Urushi's in general have been some of the best value Koetsus, in particular the Wajima, Black and the Vermilion. I did also hear the Sky Blue but wasn't so enamoured by it. It sounded very much like the Absolute Sound test report where the highs were rolled off. Not sure what was going on with that! The non platinum Onyx was a great cartridge too and of course the Onyx Platinum better still. As others have hinted, the stone bodied Koetsus are cooler sounding but resolve better.

I've not yet had the pleasure of trying a RSP, but if I may say, having tried the others in an FR64S, while working well, the highish mass of the arm started to cause some pickup of record warp etc. In this respect, the 64FX was a better match with its lower effective mass. I will be interested to know how you get on with the RSP in your 64S.

Other arms tried successfully with my Koetsus have been SME V, Graham Phantom Supreme, Goldmund T3B, Jelco 750, Koetsu 1100D mk2, VPI JMW 10.5i and the original JMW 10. I admit to being a bit shocked hearing the Wajima Urushi in the JMW 10, very open and dynamic!!! Have also heard the Urushi Black in an Origin Live Conquerer in a friends system and it was great.

I've been searching for alternatives to the Koetsus but haven't succeeded. Too many of today's high end cartridges sound like hifi and not a believable event. But as usual, just my opinion of course, and we all have one! Happy listening to all.

FWIW, I find that the Urushi works very well with a moderate, rather than light tonearm (i.e. 10 g +). I use an SME V and am pleased with the results. I have heard that the cartridge works even better with higher mass arms, but I haven't got around to sticking some blutack on my arm and rebalancing to see.

I should think than an  FR-64S or  FR-66S would be a good match.

Dear @terry9 : """   even if that remark were incontrovertibly true, which it certainly is not, it was churlish . """

Please don't feel ofended because a true and real fact can't ofend any one by the contrary: a lie is an ofense always.

You said that that fact " certainly it's not " but you give no single facts as foundation for your statement.

In the other side in many many threads I posted several facts ( I'm sure you read it at least one of my posts about. ), that no one and I'm meaning it repeat no one posted true facts that proved that  what I posted is totally wrong, why tubes and non-damped tonearms can't honor what's in the recording. If nyou have those facts please share with us, every single day is a leraning day and I'm always willing to.

As I said every one has his own audio system reproduction quality level targets and mine is to mimic what's in the recording that you can't have it with your system.

Yes you like what you listen but is far away from what's in the recording and the same for all users of non-damped tonearms.
We can't close the sun with a finger.

You like ( as many other gentlemans. ) what for many years you learnend through the corrupted AHEE ( where we all belongs. ) that still today push you and to all audiophiles to live listening as if you were living and listening a 40's audio system. You are in that jail and the AHEE has not the key to let you out, only you can do it changing your targets.

Btw, the KRSP is not a low compliance cartridge but belong to the medium range compliance.

@karl_desch , everything the same what defines that a cartridge can pick up more information ( tha's what you think against the A90. ), only one characteristic: cartridge tracking abilities and in this regards the A90 is superior to the KRSP.
Sometimes that " added information " ,  you posted , is only added distortions and not necessary true recorded information. A lower tracking level means higher distortions and less recorded information.

That we like it the sound with added distortions is a totally different issue.

As I posted, everything depends on each one of us targets.


Regards and enjoy the Music Not Distortions,
R.
