The best FIRST WATT amplifier for my systeme

[EBA]

I'm interested to build two Nelson amplifiers. I rote all the informations of his site and i consulted this forum.
I'am not shure that the best amplifier is . I want your help.
My chose : F1J

Treble : T925 A. 6860 Hz to ..... sensibility : 108 db Nelson amplifier ? actualy SE 300B Verdier.
Mid range : IWATA 2 " + Radian PB 950. 305 Hz to 6860 Hz. Sensiblity 111 db. Nelson amplifier ? Actualy SE 845
Bass : ONKEN 360 + B15EX EMSPEAKER. 25 Hz to 305 Hz. Sensibility : 100db. SE 845
Driver before the amplifiers : DCX2496 modified + diy preamp ( BUF04 + tranfo LUNDAL, 14 db and out imp 600 ohm and prépré with SK170GR).
I search a clear sound with a best fidelity of the source.

I would pick an F2J for that.

Thanks, I have undamentally the same system. It is indeed very tricky to pinpoint the right amp in the line of many, many derivatives. This helped on the further path.
