I only mentioned that you get the G 2200 so you can learn firsthand what the benefits of your mods (Wonder Caps and possible other tricks you have) would be for the G 2200. If Oeno is intrigued with your mods, he might be interested in your mods for his G 5000.
I have plenty of money, but am prudent because high end audio is a minefield of many ways to financial ruin. Even after careful research, it still is a minefield unless you listen for yourself through a friend with mutual interests. You listen in each others' systems, and he lets you borrow an item for a week so you finally learn the truth in your own system.
Don't count on money back guarantees from a company on the other side of the world. I still can't tell the country of manufacture for Giandel. It is a tough economy with many delays due to supply chain disruptions. I go into this project with the possible outcome that I lose all money spent, at best 50% assuming someone from this tiny audience will buy my stuff, but then he will know that I don't like it. I can afford to lose $1-3K on all this. So I get the best known system (A-time/Giandel 5000) at this point.
