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:




Continuous output power into 8 Ω and 4 Ω (both channels driven) >150 W (ref. rated THD, 20 Hz – 20 kHz)

Continuous output power into 8 Ω (Mono, Bridge mode) >330 W (ref. 20 Hz - 20 kHz, <0.02% THD)

Rated THD (250 mW to rated power, CCIF IMD, DIM 100) <0.008 % (ref. 20 Hz - 20 kHz)

Clipping power (4 Ω and 8 Ω) >170 W (ref. 1 kHz 1% THD)

IHF dynamic power - 8 Ω 250 W

4 Ω 410 W

2 Ω 600 W

There are better amps and you are leaving some level of performance untapped, but your current amp will work well with your new loudspeaker.

I would listen to the speakers with your current amplification a while to let them settle in and yourself get to know them.Then ask yourself what you wish to improve and search out amplification that will provide desired improvement. 

What are your sources?

I had the NAD 375BEE, and really liked it, but decided to see if I could improve. I introduced a Schiit Freya + preamp and this was a significant improvement. You might start with a preamp, the new Schiit Kara would be a low cost experiment. I also agree that you should use your existing equipment for a while with the new speakers before you make change. 

Thing is I haven’t purchased the speakers yet. Auditioning would be at the store and probably with a much more expensive pre and power amp. I know this store sells NAD products, I guess I could ask if they would have something close to mine to use for the in store audition.

If the speaker alone sounds substantially better than my old Silvers I would still go ahead with the idea of upgrading the pre amp and amp down the road.

So I get the sense that a preamp would be a more logical upgrade (with the new speakers) before the power amp?

I would definitely ask the store to demo the speakers with something similar, even if it is a NAD integrated at around the level of your separates. If you like what you hear, live with that for a bit and if you get the upgrade bug later on, you can see what your budget tolerance is and go from there.
