WTB: GC for Horns 109db 300hz up , some advice please

[siepi]

hi
i was wondering if someone here could build a GC for me ???
i am not experienced in building one myself and read quiet a few threads to get an idea what people are using .
it seems PD has found the best possible part combination...?


i would like to drive some horns 109db efficent from 300hz up .
which means i don't need a lot of power and not too much gain to avoid noise .

what would be the best recommended parts to use ?
i read people like using caddock and riken ?
what are the best power caps ? black gate N ?
power transformers , toroid ?
what is the difference between the 3875 and the 3886 chip ?

anything else i forgot for a low power low noise best of GC ?
