Is there usually a dramatic difference between $5k and $10k cartridges ?

mulveling, that’s what I assumed. No guarantee, let alone "dramatic difference".

@inna Well, it can actually be quite a significant difference, but most of it is usually "personality" rather than a difference of "quality" level. Moving coils each have a distinct sonic fingerprint caused by choices made on magnet, pole pieces, coils, wire, overall design - cantilever and stylus too!

A Van den Hul Colibri sounds worlds apart from a Koetsu. Both have their fans. There is only a small number of MC motor designs; many still use the classic magnet-yoke system which goes back to Ortofon’s SPU of the 1950s. Ortofon has used a very different motor design in high-end models since its Jubilee MC (coils mounted INSIDE the magnet in very compact form - look at MC100 or MC200 too). Clearaudios are using something different again (coils like a dumbbell with pivot in middle). Colibri is "monopole", no front yoke pole piece, which is why the motor sticks out so much (and probably contributes to its sibilance too). With the classic yoke designs, you get a classic warm "vintage" sound with "softer" magnets like alnico. Or you can "harden" it up and push it towards more modern hifi sound with neodymium. Samarium cobals sounds close to neodymium. Platinum magnets sound somewhat between the two extremes, but Koetsu bought them all up. Oh and Lyra uses a variant of the yoke, with non-magnetic pieces but an extra magnet mounted in front! I find this all fascinating.

mulveling, this sounds almost like rocket science to me.

If they sound "worlds apart" then is it possible that none of them sounds right ? Or it is more like fine musical instruments that are different but both sound right ?

Yes, that is correct - cartridges are not a great pursuit for those seeking an "ultimate truth" (whatever that is). I prefer to think of them as performance artists :) 

That's a good approach, I think, because any other one will drive you crazy.

I am also on the hunt for a new, better cartridge, and I expect to pay 2x or 3x more than the cost of my current cart.  With that being said, I will only buy a cart that provides significant improvement.

When you state "It is only 1% improvement but it got you 33% of the remaining and it is a big deal to you.", I can agree that the logic (math) is correct, but I find the premise is wrong.  

When a system improves from 97% to 98% , in your example, it is assumed that the SQ improvement will be audible and valuable .  As many have noted in other strings, slight variations/improvements are hard to notice/remember even after a few days of listening.  I expect most AGs will not spend an extra $5K (double) for a 1% improvement.  

This is not meant to be argumentative, just objective.  There are always new-folks looking for reliable, realistic insight and advice...
