Please recommend and amp for Markaudio chn-50 and chr-70.

Hello, i'm starting a new speaker project using Markaudio drivers. First a small desktop cabinet using the chn-50 in a bass reflex enclosure, for this i need an amplifier that can deliver 7 watts in 4 ohms, it can be class A or AB.

The second project will be a bit bigger, using the CHR-70 in a pensil style enclosure or some other form of floor standing cabinet, for this i need an amplifier that can deliver 20 watts in 8 ohms, i think for this one a class AB amp will be ideal, maybe something around the lm3886 chip.

What would you guys recommend for both this projects? any help will be greatly appreciated, thanks in advance, cheers
