I understood the feeling, been there, done that too. It all depends how susceptible you are to Placebo. In a simple blind test if you can honestly tell a $5,000 to $7,000 200-300 WPC integrated amp sounding better than that Crown, then go for the high end amp. Otherwise save the money and spend it on things that really count. That is on high quality (recording, mastering etc.) music that are mostly found in formats including CD but mostly in SACD, digital files 24bit/88.2 kHz and up, DSD, and a high quality external DAC. Then you can forget about the cheap price of the Crown, that contrasts the high price of your speaker; and focus of enjoying music instead.
If you are prone to the Placebo effect, and cannot resist wanting to price match those speakers, then stop thinking and just pull the trigger on a $5 to $7K separates or integrated amp, and totally ignore what everyone else said about how all reputable amps with comparable specs sound the same if working within their limits.
