Is my amp good enough?


Hello everyone. New here and looking for some opinions.

My system comprises of mostly NAD components. The pre amp is the C165BEE and the amp is the C275BEE. They are currently driving an older pair of Monitor Audio Silver 8's. I have always been rather happy with this set up.

I am now looking at upgrading the speakers to a brand new set of Monitor Audio Gold 300 5G speakers and I am wondering if my amp has what it takes to get the best out of the incoming speakers. I am not sure if I would get an honest answer from a salesperson as they might convince me I need a $6000 amp to drive the speakers.

I have included the specs on my amp and the speakers I am looking at. Thanks in advance for any advice.

Some details:

No you don't need a bigger etc amp to drive your speakers.  The NAD is a good amp.  But there are many much better (to me) sounding amps if you reach a little higher.  They just sound better.  You would get 20 options if you asked for better sound. That may or not be worth it to you.  I did not think so 10 years ago when your NAD, or my old Classe or Parasound Halo amps seemed great.  Now I have Audionet amps, climbing up their line from Amps, to MAX to top of their line.  They all sound special.  Many other great brands do as well.  Get your nice speakers and then down the road think about it.

Is “sound” not more from the pre amp than the power amp?

I was under the assumption that the amp gives the bang for the buck whereas the pre is more for how the sound shapes up, detail, sound stage, etc.

No, I would say that is not correct.  Amps have a huge impact on all of the sound qualities you listed.  Both are important.  Changing my preamp made a huge impact.  Changing my amps also made a huge impact.
