Looking for thoughts from Nottingham Analog table owners

When/if I feel the need to change from my Shelter 501 I might give classic mm a chance like a Grace or similar.
Hours of listening to the setup as it is for now though lie ahead!

Recently purchased a new Ace Spacedeck and 10" Ace Anna arm fitted with a Kiseki Purpleheart NS cartridge.  Replaced a 15 year old original Spacedeck/Spacearm fitted with an Ortofon Cadenza Bronze cartridge which I donated to a good buddy in need of a quality vinyl outfit.  Love both cartridges with a nod towards the Kiseki in that it provides more detail and a bigger soundstage than the Ortofon.  Both are sweet, highly engaging, and musical sounding cartridges which in my experience work well with the Nott tonearms.  From a practical standpoint though, the nod goes to the Ortofon.  Two items of note re:  the Kiseki; 1) the cantilever's low angle and proximity to the long and flat bottom of the wooden cartridge body creates issues with warped records which I never experienced with the Cadenza Bronze.  The architecture of the Ortofon allows for warped records to pass underneath without touching the cartridge body, unlike the Kiseki.  I've invested in a couple Vinyl Flat record flatteners and am much more careful when spinning records, being careful to check in advance if an album is warped.  As far as reported 'hum' issues, I've never experienced that with either Nott.  As far as set up issues?  Not a problem!  I have my very experienced dealer do that for me, way beyond my pay grade!  As far as the Nott tables sounding 'dark', I can't really relate to that either, neutral maybe, but not dark. That said, my preference is towards neutrality, I don't like a tipped up top end because of the etched and bright sound often associated with it on certain recordings.  I'll sacrifice the last "n'th" of detail if it means the remaining 99.999% sounds like music.  The Notts paired with either of the above mentioned cartridges provide plenty of detail for my tastes.     

I have to say my brief ownership so far leaves me with a very warm fuzzy glow!
The level of detail and soul extracted by this simple Spacearm and shelter cart is a huge leap ahead from my previous clearaudio tt.
Years of enjoyment to follow.
I would say my setup appears to be very neutral with solid organic bass and female vocals excell. Start of a long live affair hopefully!

The 2nd point I meant to make was that the Kiseki took at least 40 - 50 hours to shake the bulk of the zip out of it (my experience) - way too hot for my tastes to begin with; that's somewhere between 60 and 70 albums, then it begins to settle in.  Both Upscale and Hollywood tell me that at 100 hours I can consider it 'broken in'.  I also have a Walker Audio motor controller that the Nott motor is plugged into.  I believe the motor controller helps with the overall analog presentation as well. 

Thanks for the info especially the comparisons between the kiseki and the ortofon. Though I was more inclined to get a blue NS due to price, the ortofon's less finicky nature seems better to me and every review makes it sound like just my kind of cart. I'm also interested in charisma carts and the audio Technica art9 and the clearaudio Charisma v2 MM if anyone has any thoughts on those.
