I worked with Lou Souther 40 years ago on getting the Souther Linear Arm, now in higher end form as the Clearaudio TQx, working and practical in the field. We found that any cartridge wherein the arm-cart dynamic match yielded appropriate resonance worked as well in a linear or pivoted configuration. That is to say, there's no such thing as a cartridge that is particularly suited to LTs. If it is dynamically copasetic, it's fine in either type of arm. The Souther offered much more leeway in achieving working resonance from a wider range of cartridge compliances, by virtue of its very low vertical effective mass and still low-but heavier horizontal mass, in the same fashion as the Transcriptor Vestigal tonearm from the 1970s, or the slightly later Dynavector bi-axial arm.
In principle if the Red Sparrow cartridge works on the Vyger, it should work fine with the Odin. But to be sure one needs to know two specs I can’t find right now: What’s the effective mass of the Atlantis’ tonearm? And what is the nominal compliance of the Red Sparrow. Even Suzaku doesn’t say, nor does any review. The Odin has a claimed effective mass of 14g, so that’s middling and has latitude to take a fair chunk of midrange cartridge compliances, like a lowly Rega.
There shouldn’t be any particular special compatibility between Red Sparrow and linear trackers. Where people go wrong with linear arms and cartridges is where they go wrong with pivoted arms -- not paying enough attention to the dynamic matching of cartridge compliance to arm mass to achieve optimal resonance for the system. Linear arms put somewhat less dynamic load on the stylus assembly elastomer in the vertical plane, but an eccentric LP or a warped one, or one having both defects can still give the elastomer a workout and generate spurious signals if the system resonance is suboptimal.
The great fault of linear arms is that they are not mechanically grounded, especially air bearing ones. It does change the presentation lacking that mechanical ground. I was a strong advocate of linear as a result of helping Lou getting his mechanical design working but eventually returned to tight-tolerance-bearings pivoted arms for their more “planted” presentation.
The Galder is truly solid as a spinner. The Odin is really well executed for its arm type, but whether that is perfection for anyone is still subjective, depending on what convinces you that sound is convincing.
I use my turntables on bearings. I have to recurrently point out that if you tightly couple a massive turntable to the planet, at some point you are using your TT/TA/Cart as a planetary listening device mixing earth vibration in with the excitations traced from the LP groove. In southern California, where modest Richter 1.X tremors are happening all the time, mother earth may be shading your bass sporadically.
