The Soundsmith Strain Gauge should be considered a strong contender in the $10k range. Read the reviews and threads. For $8k you get a cartridge that many say goes head to head with the very finest cartridges- and that is when the $10k+ cartridges are used with $10k+ phono stages. The SG is a complete system that eliminates the need for a phono stage.
The SG also offers an upgrade path with several different options for aftermarket power supplies. With these the SG is said to perform at the level of some of the worlds finest cost no object phono stages.
Lastly, unlike all the other options at this level the SG is so far as I know unique in the stylus being very affordable and even user-replaceable if a spare is ordered with the cartridge. Even if ordered later replacements are still very reasonable, you just have to send the cart back as Peter matches the stylus to each individual cartridge.
