Pass’s ZV9
Passさんのアクティブロード、なんか不順な気がします。せっかくJ_FETがあるんだから、単純にSRPPにすれば良いような気がするんだけどなあ。。
Mr. Pass's ZV9 seems perfect except that the active load is too complex. It is true that it improves the performance of the system. However, we may simplify it with J-FET as simple as SRPP, by using LU1014 for its active load just like its lower side. Isn't it simple?
I think output power is not the issue for almost all home listners. I am using 10W amplifier with 86dB/W Quad ESL-57 for 1200 sq ft listening room.
