Reaching the top and stoping

You would think that by buying the top gear one would never sell it for something else, Tara Labs Zero being a example.

What have you bought that you will not sell or upgrade.

Here is my list:

1. Voyd TT Plus
2. AN IO-Gold Cart
3. Helius TA
4. EAR 324
5. HRS M3 with Spaces and Couplers. Never ever DONE!
6. Isoclean a complete system. Never ever. DONE!
7. Lector 7T Mk3 Only good for cleaning the house and
making Love anyway. No need to upgrade ever.
