Feickert blackbird, kuzma 4 point which cartridge

Larryi, not only does VTA/SRA matter with the Titan i, azimuth matters at least as much. This is true of pretty much any cartridge with a line contact stylus profile.

Essentialaudio,

Yes, the line contact styli I have used are extremely sensitive to changes in VTA/SRA. I know that many claim that small changes should be inaudible, but, my experience is otherwise. Making very precise changes of well under 1mm in height at the tonearm pillar on a 9" arm makes a clearly audible difference.

I do use records of regular thickness to set the VTA/SRA and then I don't bother to make changes for different records.

Vta matters in Titan, especially for thick records. i have got nearly 1000 records. % 60-70 old records, % 30-40 new records(most of them 180-200 gr). Last night one of my friend and i was listening mofi frank sinatra at sands. it is a great concert and also a good recording not the best but very good. When we listened first i thought that i must have been remembering wrong about the recording quality, because it was muddy. When i had changed the vta, everything changed. i am planning to find an optimum vta heights for thick and normal records.

In your list I found that Lyra Titan would be a great choice, detailed and open; less richer than Koetsus and Shelter 501/901/7000.
I own a Feickert Blackbird TT and sounds excellent with a Zyx 4-D cartridge (also known in US as "Atmos"), but my tonearm is different than yours (I got a Reed 2A) so my listening opinion may not useful to your experience.
Good luck for your choice!

Marco zyx omega was a another choice in my list. i am quite sure it goes well with kuzma, i think kuzma cartridges made by zyx, so they may match well i suppose. Lots of reviews of 4point made with titan, thats why it is number onenin the list, also i found a very good deal. Next run i am planning to buy koetsu or shelter for stogi ref313 for a diffrent taste, but who knows maybe omega :) i hate being an audiophile :)
