Getting The Most Out Of A Koetsu Urushi


Recently acquired a Koetsu Urishi Tsugaru from a known and well trusted source. This cartridge has been refurbished by VDH, and has under 100 hours on it. Mu current cartridges consist of an Ortofon Winfeld, ZYX 4D, and Denon DL 304. 

The Urushi is certainly different than my previous cartridges, and I do hear lots of potential there. Currently have it installed on a DP 75 in a VPI plinth, with an Acos GST 801 arm. Phono stages available are the Liberty B2B-1 and the internal stage on a Musical Fidelity Nu Vista M3. 

The question is system configurations on how to get the Urushi properly sorted out. Are most Koetsu users also SUT users? Is there any upside to running it on this cartridge versus my phono stage in MC trim? Secondly, the output cable on the 801 is not verified as the stock one for the 801, and since the arm is wired internally with silver wire, I have considered the possibility to changing it out to a known cable of good quality. Which that one is to be, I have not made a decision on. 

I do also have a Technics SP 10 MK II in a variable density plinth, and I might consider putting the Urushi on there, although it might necessitate a change in tone arms. I have a 12" Riggle String Theory arm on it, and I suspect the wood arm may fall into the slightly warm camp, which is not what I would suspect this cartridge needs. It does seem that the SME V is a go to choice, but been thinking of other options also. 

Anyone with thoughts and experiences they care to share?

On the subject of effective mass, my Triplanar has effective mass in the same range as the SME V, about 11g, I think. My Urushi sounded very good in the TP, but I have always wondered whether it will sound better in a heavier tonearm.
@lewm teh effective mass of the Triplanar can be adjusted somewhat by using a different weight combination.
This manufacture utilizes a very low output (mV) design strategy. What is your current loading and gain setting on your phono stage?
The loading is for the benefit of unstable preamps and does not affect the cartridge.
If the phono stage is stable, 47K will be fine.
