I put Coralstone Diamond on Koetsu SA 1100 MK VII and his headshell.
The headship has the litz Acrolink 8 N
Turntable is TD 124 Schopper
I know for this cartridge will be better Techdas,Kronos,ecc with SAT,Kronos,Axiom,Elite,and i will be very curios to listen Koetsu there,but also in this set up is wonderful.
With other cartridges i have i am exciting for their character,but with this i think only listen music because all seem perfect and sound is very natural and musical
Listening this i don't regret Opus 1 for his deep bass and depth,Atlas or GFS for dynamic and high
Even high are very good and i don't listen any roll off
Phono is CH P1 with X1 in current
I read in some place you like a dark sound,so i think this is the cartridge for you,
there is no roll off and is no dark,but have no the high of Atlas or GFS,is perfect from mid bass to mid high and has good bass and good high
Then if you have Cessaro that is medium high efficiency like mine the sound is free to come out from the speaker in natural way
Your Koetsu Coralstone looks wonderful! Such a nice one!
As you might have seen, I using Koetsu Stone Body too, the Onyx. I am trying around with headshells and cables. So 8N Copper with Koetsu is a wonderfull combination.
On my Jelco HS 30 headshell (similar to your Koetsu) is the same thin rubber ring fitted, as I can see on your headshell. My 2 arms (Ikeda and FR64s) do prefer the headshell without the rubber ring, my be you like to try it, for me this in a little bit increasing the dynamic of and the energy of the cart. As the Koetsu carts do have a metal top, I tried the Dereneville Minimat between Cart and Headshell. In my system I got a little better contour, which I finally preferred.
I hope, that I will have the chance to try out the Koetsu Tonearm , looks very beautiful in your set up with your Thorens version.
Opus 1 has same tonality than Coralstone,and sound is very similar.
Coralstone seems little better and natural on mid and on voice,
Opus 1 little better on deep bass and high
Opus 1 has advantage output that is 0.5 instead 0.2/0.3 of Koetsu
If one can have 2/3 tonearms,Coralstone is fantastic for voice,and few instrument like chamber music and jazz trio
i heard in Munchen demonstration of Gryphon Kudo that are similar to Pendragon with their incredible bass tower
so consider also Opus 1 that has a incredible deep bass,better than all other cartridge,
bass will be wonderful and sound similar to Coralstone
The Opus high to my ear is as good as Atlas SL. But the cart is full body, more dimentional and more depth. Details are all there in the Opus but doent like to "show off" like Atlas SL. Do you think so Gian.
