Ryssen: IRFP260N works perfectly fine in Mini-A, I made a pair of mnoblock for a friend a couple of years ago with those transistors and they played ruler straight all the way up to 200kHz.
Also, I believe Nelson has mentioned that high current, high gm devices are benificial for the bass response.

Lineup: In my first post there is a link to another thread, that a look at the first schematic in that thread but donīt look at the component values.
No transistor in this project will dissipate mor than 35W so there is no need for parallel devices.

Hi Fuling.

Right now I`m working on "similar" single ended class a amp...
I think the issue here is this:

1.Capacitance of the mosfet or any other transistor is reduced when cascoded! How to calculate this reduced capacitance.

2.It is important what would drive the mosfet.

3.Is there any real "sounding" benefit of cascoding in this case?
