I just got a set of Decware el84 amps, using one right now. 2 watts, and with N3s speakers at 91 db. They actually sound very good. BUT, I can not get them REALLY loud, loud yes, great at low levels, no home theater music coming from these. I very much enjoy them though. Open sound and great for all types of music. Go for it. 8 watts should be ok.
