I haven't seen a lot of people post about owning either of those cartridges, so your chances of hearing someone's impressions of both are probably slim.
Here are some things to consider. Your turntable is probably the weak link in your analog chain, not your cartridge (IMHO). The Hana SL is very nice and you have an excellent phono stage from everything I have heard about it. I own Herron monoblock amplifiers and they are spectacular.
The Concept is a decent turntable, but that magnetic tonearm isn't something I'm crazy about and I don't think the table itself is very well isolated. I owned one briefly, so I'm speaking from personal experience.
I have the Kiseki Blue NS, the cartridge below the Purpleheart. The Kiseki Blue is better than the SL, a little more airy and detailed, but not by a huge margin. I have heard of some Purpleheart owners mentioning quality issues. I suggest doing a search on that.
Putting an expensive cartridge on an entry level turntable isn't necessarily a bad thing. I currently have my Kiseki Blue NS on my Technics SL 1200 MK 2 and it sounds really good.
I have a recently retipped Zu Audio Denon DL-103 (which I think was about $400 new?) on my Acoustic Signature Wow XL and that combination sounds better than the much more expensive Kiseki Blue on the Technics. The Kiseki Blue didn't significantly outclass the Zu DL-103 when I had it on the Wow XL, but it was definitely more refined and clearly better than the Zu on the Wow XL.
In short, my experience has been that upgrading the turntable provides more improvement than upgrading the cartridge. They both matter, but my experience has been that putting a really nice cartridge on a less than solid platform (table and tonearm) is going to result in less of a sonic improvement than putting a modest cartridge on a well engineered turntable and tonearm.
