Class D is just Dandy!

I thought it was time we had a pro- Class D thread. There's plenty of threads about comparisons, or detractors of Class D.

That's fine, you don't have to like Class D amps, and if you don't please go participate on one of those threads.

For those of us who are very happy and excited about having musical, capable amps that we can afford to keep on 24/7 and don't require large spaces to put them in, this thread is for you.

Please share your experiences with class D amps!

I looked at the NuPrime pages VERY briefly. NuPrime’s tech sounds a lot like the Yamaha EEEngine. Small class A amplifier sandwiched between Class D voltage rails.

Again, kind of goes back to Carver’s Magnetic Field amp and NAD’s switching rails technology.

Sure gets grate reviews. I would love to give them a serious listen to see what the benefits really are.

I mean, it’s quite different from Hypex/Pascal/B&O but I have no idea if it’s much better.

The challenge with this kind of hybrid approach is again, you rely on feedback to tell you everything about what you should do from instant to instant. With the voltage rails swinging at the same time the Class A amp is swinging it is like shooting an arrow from a moving boat.

@madavid0, how many hours of break-in did you give the D-sonic amp?

Thanks, Erik, great info. I had no idea it might mimic or be similar to other designs.

It’s my first adventure with class-D so I have no idea if it’s better or even as good as Hypex, B&O or Pascal. I do know I like everything about it so far. It’s the easiest amp to listen to since my octal pre/845 SET combo. Refined and smooth with no listening fatigue at all.

I hope you do check out NuPrime. Would love to get your thoughts on how they fare against some of the competition out there.

Keep it coming, guys. This is a great thread.

Cheers,

Scott

Yes, George, Bel Canto Ref 600Ms are very good.  I  am right now listening to absolutely splendid sound of Mozart Symphony #40 with them driving  Focal Alto Utopia Be speakers, sourced from Esoteric K-01 through an ARC LS 25 Mk II pre.

I could not be happier with the sound quality.

Guys,

I'm so very happy with all of the participation on this thread, I'm also learning a lot, since I don't get to go to shows and dealers and listen as much as I would like to.

Would it be worthwhile to put together a web site JUST for class D amplifiers? It might give me the chance to listen to a lot more gear as a regular review feature, and break the mega-linear-amp stronghold.

It's just an idea, a lot of work if I chose to.

Best,

E
