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:

try a used hegel... a cut above nad sonically, as an amplifier

h190’s have had a recent price cut... a steal a current used prices for the performance to be had

I’ve seen this brand mentioned a few times. The few high end stores I frequent don’t seem to carry them. I will look around. But the more I read hear, the more I trust I will be happy with the NAD….for now.

I am pushing Monitor 300's with a 100 watt Benchmark AHB2 just fine. I agree that you should take the time to audition the speakers with the amp you have, before you upgrade.

Room size is very important. Bigger rooms offer more challenges, ceiling height is also really really important. And the color of paint on the walls also impacts your ability to perceive sound. 

Also found the more money you spend the happier you are. It's mostly due to positive reinforcement.

Survey says.......Your amp is good enough. Yet, like others say, listen until the new speakers are broken in well.  Then, consider the plethora of better amps out there.  Upgrading is part of our fun is this hobby.
