if these are rated at 87db i would think you need more juice, in whatever brand you choose. obviously nad is more affordable so perhaps a larger nad would do.
I'll take that Johnny...I owned various nad amps and i liked most of them. My point is simply that an 87 db speaker and a 50 watt amp is not the greatest match out of the gate. Thats why i recommended the same approach as you, up the power of the nad.
