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...

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

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

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.

Thanks much for the information! Nothing to do with the quality of their products, but I checked out the Apollon site and they wax more eloquent and use more "audiophile" descriptions of their amps' sound quality than many other manufacturers! What's the difference between Hypex and Purifi...

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

It must have taken real work to deign a three way bookshelf speaker with an impedance curve like that. It is totally unnecessary apart from being design malpractice.

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...

As PENG‘s excellent string illustrates it makes sense to buy Class D instead of Class AB. Buckeye is here in America and is, or tries to be, the most economical. His cases are a little too budget oriented for my liking but the internal modules are pretty well standardized. His amps get...

Does the dealer where you bought the Marantz AVPs sell KEF? Have you listened to their active speakers?

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...

That seems like a 5th grade explanation after 'the class' but technically, it's true. They could have mentioned XX and XY chromosomes, but I'm not sure enough of the population would have understood.

...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... ;)

I love the comment - "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" I think many of the class D amps on the market would fail that test...

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...

I went looking for the Nobsound NS-04G PRO Mini Digital Power Amplifier HiFi Stereo 2.0 Channel Class D Home Desktop Audio Amp 100W+100W and get this: Amazon has it for $401, This must be a mistake. AliExpress now has it for $40 (was $35 yesterday) which includes power supply. My problem is...

...focussing on the room and speakers more, based on audible sound quality benefits. In terms of objective measurements, in absolute term, class D amps such as Hypex, Purifi, and some ICE based amps such as Marantz Amp 10, 20, and other well measured ones, along with Benchmark's class AB...
