Looking for a New Cartridge


I have a VPI Prime signature. I have a Koetsu black goldline and never thought it was a great match compliance-wise. I confirmed my suspicions when I purchased an Ortofon quintet black as an interim/backup cartridge. It really sings from top to bottom and was much easier to dial in, where the Koetsu required constant adjustment (don't ask me why).

I have the itch and am looking at the Ortofon cadenza Black (don't think Bronze because of my sonus Faber speakers), kiseki purpleheart and I was offered a deal on a lightly used air tight mc1 Supreme which I don't know too much about. Another suggestion was the air tight pc-7 which is impossible to audition.

Looking for suggestions/recommedations

Thank you all and have a great holiday.

I have the Prime Signature with the Cadenza Bronze base on VPI’s recommended cartridges for it, and the sound is fantastic.  I do not see why you would be disappointed with the Cadenza Black, but wonder why VPI did not recommend it over the Bronze.  Possibly about the same performance for a good bit more money??  You might want to contact VPI directly, and get their input. 
I have two VPI Prime Signatures and have used two Koetsu carts,
the Vermillion and the Rosewood platinum Signature. Set up properly both sounded great. I also have used several Benz Micro carts and their sound fine but bright. Finally I settled for two Van den Hul carts- the Stradivarius 
Signature and the Stradivarius Master Signature. They simply are outstanding. Each of the carts were not that difficult to set up if you know 
how the arm works. However each cart has a very different signature with the Koetsu being warm and less detailed. My belief is that the VPI arm will accommodate most carts. I suggest adding the Soundsmith
weight system to make the setup easier. Choose the cart that sounds right to your ears and set the VTA properly.  Some carts like the Soundsmith and Benz are very bright and others are more balanced.
Anyway since your VPI is a state of the art turntable, it is the cart that will
have the most impact on the sound. 
Browndt thank you. I also think that the soundsmith is a little not to my liking. I will see where I can audition the VDH. The problem with buying a new cart is it is a blind purchase most of the time. I am in the NY tri-state area and find it hard even here to find a retail store that has more than a couple of cartridges set up. Unless you have a friend that has what you are looking for already it's tough 

My journey continues.

Just received Music Direct brochure in mail today they are doing 50% of all soundsmith cartridges, if I didn't have 2 SS and broke after Christmas I would buy one.
