Hi Joules,
Thanks for your inquiry - very interesting question!
I have no immediate plans for a very high power AKSA. There are three reasons for this:
1. Lots of R&D, with attendant high cost of development;
2. Small market demand for such a product, and
3. Rapid development of highly efficient Class D and T amps which would nicely fit this bill.
I will, of course, keep you posted!
Cheers,
Hugh
