So far what I have heard in my system is somewhat slow, kinda dark, not a lot of "air". I do hear a very solid image, very meaty big sound, but it sounds more like a spherical stylus Denon 103 than a $$$ MC cartridge to me.
This is one of the best descriptions I have heard of the Miyajima stereo. Their monos are good but this is exactly how their stereo sounds like. I never understood the hype and I call it Muddyke because of these exact attributes.
There are many better carts at similar lor lower prices. SPUs do the bold sound way better. Hana SL, Audio technica Art 9, are lesser priced, and more neutral, with more musical information. Allaerts boron mc2, you will get that used at a similar price and is excellent.
Lyra and vdh are much more neutral than other carts, and here you can get into a whole discussion of what is neutral, what is too much detail, and what is musical, but if you liked the Lyra, then the Lyra carts became more musical with the introduction of the Lambda, though that is more expensive. You might want to look at vdh crimson stradivarius to retain neutrality, get that fast detailed cartridge you like, and imo more musical than the Lyra, and the crimson used will be priced very competitively. However due to variances in samples pick one only if you get to hear it or ask the seller to send you a video .
If you could afford 8.5k euro, half paid now and half on delivery after 6 months, I would jump straight to the DaVa field coil cartridge. It works great with Kuzma too. It is sold direct from the manufacturer so no built in retail margins, margins to create additional samples to distribute to reviewers, etc. It had a one year waiting period last year so the manufacturer stopped taking orders from Oct 2022 - this May, but now it seems to be back at a 6 onth waiting. You will need an additional SUT for it, and the field coil cart means you will have to put two wires along your arm, to do which you will need to be willing to get your hands dirty, or get someone local to do it for you. So factor that in. You can read up a lot on DaVa and the attributes on this forum so I will spare you that on this post.
