Miyabi Red Rose anyone heard ?

Has anyone heard this variant of Miyabi cartridge ? It was made by Takeda San for Red Rose (Mark Levinson) and supposedly one of the latest cartridge made by Takeda San. The specs of this cartridge is as follows:

Output voltage: .24 mv (1kHz)
Source impedance of coils: 4 ohms
Head amplifier: 1000 ohms
Recommended load impedance:
Step -up transformer: 4 ohms
Frequency response: 20Hz ~ 40 kHz +/- 1 dB
Channel separation: 25 dB @ 1 kHz +/- 1 dB
Cartridge mass: 13g
Compliance: 8.5 X 10 6 cm dyne
Recommended stylus pressure: 1.7 ~ 2.0g
Stylus design: 8 x 40ยต line contact
Magnet type: Alnico

From specs it looks very similar to the Miyabi Standard cartridge but how does it actually compare to the standard ? Anyone had the opportunity to audition this cart ?

Dear Pani: I owned the RS-A1 and you are right: it's better that what it looks but IMHO nothing more than that. The important subject is that it fufil your needs/priorities on music sound reproduction.

Nandric, for your post seems to me that you already listened to the MD and you rated at the top. Is really that good?, for what I heard through my Spectral cartridge and if my memory does not " falls " this Spectral beats the MD but maybe I need to hear this one " today " in my system.
Anyway, good that your MD is running in your system.

regards and enjoy the music,
R.

Hi Raul, I forgot to mention that I also use one MM cartridge which is the Empire EDR9. I bought it after reading your thread. It is nice but it doesnt beat the top MCs in my system. Possibly I dont have the right tonearm for it. The 47 Labs tonearm is a medium-high mass so the MM carts dont like it. The 47 Labs is very good with cartridges with compliance between 5 to 12. I am surprised how good the Denon 103 anniversary sounds on this tonearm.

Dear Raul, You know that I trust your ears and not your
philosophy. My first impression is that Magic Diamond is
too good for me to judge. I am an amateur in this hobby ,
not musicaly educated with average hearing capability.This
cart 'deserves' the so called 'golden ears' in my opinion.
I wish you was my next door neighbour. In no way I consider
to post the cart to Mexico but I should in some
'objective sense'. That is btw what private ownership is about.

Raul, one more thing. After hearing MM I know one thing clearly. There are some areas of music reproduction where MM excels over MC, no matter how good the MC cartridge you select it cannot beat the MM in those areas, possibly because it is a fundamental strength of MM technology. It is like comparing Ink Pen to Ball point pen. I would love to listen to a London Decca cartridge some day.

Dear Pani: Agree, the MM/MI is an alternative that all of us could try.
