It's important to know at least the nominal impedence of your speakers (in ohms). 4 ohm speakers require twice the watts to produce the same volume as 8 ohm speakers. But speakers typically have an impedence "range", ie from 4 to 16 ohms. The power rating of amplifiers are typically based on how many watts they will produce into an 8 ohm load. But when amplifier shopping, I want to know (at least) both the 8 ohm and 4 ohm power output of an amp. Your 130 watt receiver would rated for an 8 ohm load, and it may not put out any more than that into a 4 ohm load.
I use a McCormack DNA-2 Rev. A that is rated at 300 wpc into 8 ohms, 600 into 4 ohms, and 1200 into 2 ohms. My speakers have a noninal impedence of 5-6 ohms. I do not consider this to much power, and I agree with Bob B. above that too little power is worse than too much. NAD amps typically have "stiff" power supplies, but you'd still want the bigger one, especially if you like your music loud. Good Hunting. Craig
