Well I've got a Thorens (TD160S) turntable with the very modest VM95E cartridge.
It sounds great, but I'm the last person in the world to be advising you.
That's because there's more chance of me being the first person to set foot on Mars than there is of me ever spending $1000 on a cartridge.
I reckon the VM740ML that Paul recommends in post #21, could be good - and it's the most I would be spending in your position (even with $1000 going completely spare).
In fact, I have to wonder whether your receiver would allow you to fully appreciate the difference (such that it may be) between that and a VM95ML.
Yeah I have the thorens td145 and it sounds pretty good! I would like to upgrade everything else over time so thought going with a good cartridge would be a good start. I checked out that at cartridge and it sounds pretty good, and the Nagoya cartridges sound intriguing as well.
