Yamaha1: If the HCA design is class A or not, can be discussed from here to the moon. In pure theory, it is not - In real life, maybe. Is it the ears or the book who decides and who's ears, what is real? And if Krell proclaims class A, well doesn’t really change the discussion.
And yes Yamaha did develop HCA for the “cost no object” MX-10000, I am not saying any thing badly about the design, it is tremendous. But did they also use it in the even more costly and also “cost no object” GF-1, this I think is interesting.
ExJxC, you lucky man :thmbsp:
