I recomend CAR if you have a tonearm that can handle the weight.
I have used Benz LP, Benz Glider, Benz ACE L, Hana Umami Blue, Scheu MC among others. I really love my CAR-30 and now I just recently sold of my spare Benz Glider and I’m ready to buy the next main cartridge for my StabiR/4-point 9”. I’m pending between the CAR-40 and -50. Haven’t decided yet.
I took my CAR-30 over to a friend who has the exact TT setup but the Unami Red and a Koetsu rosewood signature and we compared carts. To my surprise the -30 didn’t make a fool of it self. A majority of the people there preferred CAR-30 to Hana Red including myself, even the Koetsu had a hard match.
In my ears there was no clear winner because they where all excellent cartridges. But the CAR-30 had more pace, more big dynamics and sounded more dramatic then the other two. I liked the Koetsu a lot, it was surprisingly detailed and crisp to my expectations. The Hana Red was the least likable in my ears on this system I must add. It was the brightest of the three, a lot of details but not as grounded as the two other, no real momentum.
It all comes down to system and subjective preference I suppose.
Keep us updated.
