...8 ohms and 500 watts into 4 ohms with SOTA noise and distortion performance. It’s also gorgeous and weighs a hefty 74 pounds despite being a Class D, high efficient design. Marantz has done some slick things to make it a unique offering such as: Latest generation of HDAM preamp circuits...

I don't dispute that the AB amps are most likely excellent, but they are still inefficient and heat generating amps with the best class D amps performing better (not audibly, likely).

...AMP and it seems to measure well. 100 watts @ ohms is no slouch, but it is Class B. 83w at 8ohms. Every amp I have owned up until the ATI Class D has been class AB. (Anthem, Parasound) This amp is only class B, is there any disadvantage to this? At $299.00 the Topping B100 seems like an...

Parasound was sold by it's founder in December 2022. I'd guess that it will not survive despite the new owner. Once class D amplification became a mature design, all older designs got notice that they had to find new ways to cut costs, join the class D bandwagon, or go the way of the dodo bird.

Oh, right. I was looking at their $8K SDR-35 AVR, which is class-G, and I assumed their 9100-AVR was also class-G. So their class D and G must be very small and light.

I have five class D two channel amps and at least one sub plate amp. I can't tell any particular difference with my class AB or G amps. Don't know what you expect in terms of dynamic range or "clarity" whatever that is.

I agree Parasound is done.

You mean amp class (A, AB, D, etc) ? Or specifics within an amp class?

Very few watts. Even 10 would blow your ears off with any regular speakers. "84 dB" if that's even accurate...still quite loud with 10 watts. What do you mean by "everything"? What inputs/features do you need that a small class D does not do?

I left Anthem MCA AB amps and went to Class D 5 years ago. I now have smaller, lighter amps that run cool and that have SOTA bench measurements. So why would anyone use AB other than nostalgia? Check out ASR’s comparative bench measurements of his top reviewed amps. They are Class D with a...

Definitely fully active crossovers with BW limiting for each driver which is directly coupled to its respective amplifier.

Wouldn't that more depend on particular execution? Class D can fail, too.

Has to be an active crossover seeing as how each driver gets its own amp. Class AB can be very good. I am sure there is a reason why Focal/Naim went with class AB over class D in a no-expenses-spared loudspeaker.

At one watt it won't be pretty unless it uses Peter Walker's current dumping topology, which uses a small class A amp in a feed forward mode to correct the dumpers. I doubt it does as they would be too stupid to figure it out. That amp is junk. Avoid.

For your spec. then you are pretty much going to have to go with class D switching amps. You are not realistically going to get the power you require without going class D to get the efficiency. The Mac can manage it because of their use of auto transformers. They are essentially using tapped...

Wow. Lots of Class D stuff. Do all of you guys use Class D? I've read reviews from "Pro" reviewers but I always have that thought in the back of my mind "Is this guy getting paid by the company to review this?" I'd be really interested to hear from people who actually use it on a regular basis...

...do have to say this thread has gotten me think otherwise, and that I need to do some homework so I have a better overall understanding of how class D works (like what are the “modules” that were referred to, the differences in power supplies, and that kind of thing) before I make a decision...

So, umm you done went and picked up some of those fancy class D amps huh? Umm how about this! Sell to me!;) 3 of them Outlaw Monoblock amps you got no use for? I'll pay shipping! :D. Plus you can use the funds to by more class D amps.;)

...AVRs are Class G assembled in Vietnam, same factory that builds the Audio Control products. The subject lineup is a totally different platform, amplifiers are Class D, DSP is a 4-core Cirrus Logic. The source is in China, same factory that builds Cambridge & NAD products.. Just my $0.02... ;)

Warranty on these are usually 1 year to 3 years. ATI class D are still 7 Years warranty. One thing I haven’t seen from class D (for mainly academic and amusement) is how they perform on the 1-ohm test. I want to see someone take an ATI class-D amp that weighs 65 lbs and do the 1-ohm test. :D...
