Should I steer clear of class D amps

Very true and I am looking back but this amp only hit the shelves a week or so ago, Cambridge audio recently introduced some tech called Hypex Ncore (the word hype isn’t lost on me) nothing more than sales pitch about that, nothing meaningful.

Im not being lazy, this is a new amp and despite asking NAD a bunch of questions via email I’ve had no response. 
Ears do trump all but due to personal circumstances I really want to limit having to return anything, I also am unable to go demo one.

I’ll look into the hybrid tech you mention, I didn’t know about that, thanks for the pointer, it’s not mentioned in the blurb for the C3050 though. 

Check out the Music Fidelity 2si.  A good sounding line level integrated amplifier in your price range I believe. Class A/B. 

OP:

Well most of your post seems related to Class-D in general, and the title was about Class D, not NAD, and those hesitations and questions are roads well traveled here.

NAD has promoted a hybrid-Class D in some amps, but not others, so I’m not sure if it was an experiment that didn’t go far or if it’s become core, or if there wasn’t enough benefit vs the basic Hypex Class D amplifier designs they are using.

Honestly I thought they did a poor job of promoting the hybrid part. My desktop 3020D for instance is one of those hybrid designs and it’s great but I don’t really challenge it.

My suggestion, which was implied in my first post, is to ignore 100% of the literature on Class D and actually listen to the amp you want to buy, preferably with the speakers you want to buy.

If it helps, I went from Parasound to Class D to Luxman.  At no point in using the Class D amp did I think "Oh, well this is a problem unique to class D", or "this sounds like class D."  so I encourage anyone thinking of buying to stop thinking Class D vs. the world and focus on budget, features and sound quality that you can actually hear. 

I am an old audiophile and must admit to being suspicious of this completely new class if amp when released, particularly as they a flea weight.

When first released there was a lot of hype about perfect sound and then a collapse as everyone realized they just didn’t sound that good. Then year by year they got better sounding. I have heard some contemporary Class D in my system. They can sound very good.

But the thing is, it depends on exactly how much you have to spend, your musical taste and system. Say you have $X to spend… maybe there is a class D that would be the very best sounding amp for you… but had your budget been $2X then some class AB would have been the best for you.

So, I would not stay clear of Class D. You need to carefully audition any high end amp to be sure it has the sound you want and fits in with your system.

Class D is good stuff these days. Try it and find out for yourself if interested.

I started with Class D about 14 years ago in part as an experiment prior to adding more tubes and never looked back. It’s even better technology today. All tubes are now gone. No regrets.

I run a Cambridge Evo 150 and an older Bel Canto c5i. Both are always dead quiet …zero noise issues if that helps put your concerns to rest.

Have heard other NAD Class D and can highly recommend.  The new integrated with the meters caught my eye and looks way cool.
