Hello Altec Best - for now, I would keep the 802-8gs in case I ever have to go back to stock, either because I like them better than the TAD (cannot see how this will be possible based on my prior experience with my TAD4001-based system) or to sell M19s as stock.
For example, I might have to sell if someone can lend me 25K to buy:

Will keep folks alerted to my progress in the future.
Sincerely,
Don
