I'm going to build power amp and I don't know which one can be better. I've designed 3 amps. First with BJT transistors, second with HEXFETs and third where signal goes trough MOS and cascode transistors were BJTs. All are designed without overall feedback.
I don't know which one to build, because I don't have enough money to build all of them so I have to choose one (the best).
Amp with MosFets I designed after I've seen Nelson Pass's patent for X-series. My design is similar but I use cascode transistors, symetrical input stage(both P & N), it don't have so many current sources and output stage is biased for class A to 6Amps.
My BJT amp is similar to well known LC Audio - The End Millenium but with more output transistors,with cascode transistors and output transistors biased for class A.
The third one was something between first and second.
Can someone help me to choose which one will sound best. I think that the best is with MOSFETs because has much less count of gain stages than others.
Thanks
