Of the two

Which is a better choice for Rainmakers, EPOS elan 10: nad 7175 pe or Carver 732? Mostly into light rock jazz, blues. Thank you.
What's your budget? I don't think either receiver will do justice to a pair of Rainmakers...just my opinion.
Thanks. What would you suggest for a moderately used amp or receiver?
I'm having an NAD 7400 reconditioned (pots etc. )any better, or should I scrap them for new or moderate price wise? I need direction as a novice.

If your NAD 7400 has enough power to drive your speakers properly, I would say get a new preamp instead. It should make a bigger difference. The amp and preamp sections on your NAD are jumped externally. That allows you to bypass the preamp section of your current amp altogether.
