@lewm , @chakster , I do not think stability with removable head shells is a problem at all. They lock down tight. I do not like additional contacts with low level voltage devices and I do not like the additional mass it entails. Regardless of how light a removable head shell set up is it is lighter without it. I also do not like low compliance cartridges. Given the exact same stylus a low compliance cartridge will wear out records faster than a mid or high compliance cartridge. Just a fact of life. I also think more compliant cartridges generally track better. I think multiple tonearms and/or turntables is a better solution if you are using different cartridges for mono and certainly 78's. I did the multiple cartridge deal for years and what happened was I always listened to the one I liked best and the others sat hording money I could use for other purposes. I now have a collection of 78's to deal with and eventually I will record them all to the hard drive via Channel D's program. I already have a 78 cartridge for that purpose. I do not switch cartridges for the few mono records that I have mostly jazz from the early 50's. All this amounts to personal preference nothing more.
The Cosmos is on it's way. It will arrive this Tuesday. I have started prepping the arm. I fashioned a finger lift and a locking arm rest for the Schroder. Mr Schroder does not like extraneous stuff hanging off his tonearms. The arm rest will mount to the Sota's plinth and the finger lift was added to Schroder's cartridge mounting plate.
