How far away do you sit?
If sitting ~10ft away, 75W RMS into 8ohm will give you at least 100dB. I usually recommended not running amps at full tilt, so I would suggest at least 100W RMS into 8ohm.
It you want, you can always use the Ragnarok as a pre-amp, and use the RCA/XLR outs. James Romeyn assembled NC400’s will run you $1500-$3000 depending on configuration (single stereo, monoblock pair, bridged monoblock pair).
