Linn Ittok IV II - The Best Cartridge Match ?


I have an Ittok IV II on a Cirkus'd & Lingo'd LP12 an plan to replace my K18 with a good MC cartridge.

The following choices have been recommended:

-Audio Technica OC9 (newest model)
-Audio Technica AT33PTG (More detailed?)
-Denon DL-103R
-Denon DL 301 II

All of these cartridges seem to offer good value, but I'd like to know which might make the best match with my LP12 setup. I have heard less about the AT33PTG than the others, it may be less forgiving to certain recordings, but seems to offer the type of sound staging I like.

The Denon cartridges don't advertise frequence response below 20hz and also track heavier than the Audio Technicas'.
Are these specs really significant?

Any feedback on these cartridges, or other recommendations would be appreciated.

I started out with the OC 9, then moved to a Benz Glider, and now I have the Shelter 90X. Like you I have the Cirkus, Trampolin, Lingo, and Ittok LV II. You may already know this but the 90X is in a different league than the others I mentioned. What phono stage do you have?
I have a Kairn with Brilliant Power Supply. My well worn K18 actually sounds pretty good, but I always knew I needed to update that part of my system to an MC. The more I hear about the Linto, it seems to offer good value as an upgrade. It might be better to leave my old Lingo Version 1.0 alone and get the Linto and new cartridge first?

I have ruled out the OC9, if only because of positive reviews of the AT33PTG, for slightly more $$. The AT33PTG sounds more detailed, with better midrange, good tracking and no preference for any type of music. There are some positive comments about the AT33PTG at this link:

It's good to learn that there are a few well regarded MC's that will work well with the LP-12 without breaking the bank. I am aware that the Shelter 90X or even the Shelter 501 are a step up from the AT's, but for now I am thinking that an upgrade to a Linto,(Lingo II eventually), and perhaps an AT33PTG might be a good way to get started. Perhaps one day I would move up to a shelter 90X, but first I have to take a few 'BIG' small steps.
What phono stage do you have Xagwell? I have a Cirkus, Lingo, Ekos with a Linn rebuilt Troika from 1998. I am looking for MCs that match well with the 150 Ohm Linto.
I started out with an Audio Research PH-3 that I bought in 1998. I changed the stock Sovtek 6922 for Tungsram which really extended the bass. In April of 06 I upgraded to an Aesthetix Rhea. I really enjoy the sound of tubes so all my gear is tubed except the digital front end. Sytem matching is so important especially at the cartridge/tonearm. I invested in The Complete Guide to High End Audio, by Robert Harley many years ago. Chapter 9 is "the LP Playback System. I still refer to this book when I am in doubt, as well as consult the Agon community.
I have the same setup but no circus and lingo and have the newer Koetsu black. I am getting great detail as well as the magic koetsu's are known for i.e.: the great midrange holographic imaging etc.
