class ab vs class d sound

My first thought is that a class D would have less audible harmonics. About Class D Amplifiers Class D amplifiers take it a step further and they are even more efficient and less hot than their AB counterparts.

Things like the Emotiva XPA series or the Red Dragon M500M1000 come to mind.

. In Class AB you have actual audio coming through the entire amp where in D its converted to a PWM signal at some point. Given the common bias against Class D in 2-channel audio it would be interesting to see some comparisons between similarly priced Class AB and Class D power amps. Superior sound quality means better reproduction of the input signal therefore less THD and less intermodulation distortion Generally better design because theyre usually discrete unlike most class D amplifiers which are implemented not designed which leads to better quality components.

To me class D sounded smoother and less splashy darker than class AB. It depends greatly on amplifiers used. Ive still yet to hear Class D sound natural but I have heard several AB amps deliver in that category.

The subs all have BASH amplifiers which have a Class D front end and a Class AB back end - so you get the minimal power draw associated with pure Class D amp designs yet you retain the traditional sound of Class AB amplifiers. While a Class AB amplifiers efficiency improves as it approaches maximum output Class D designs maintain a high efficiency rating over the majority of their operating range. Up to 17 cash back Class A design is the least efficient but has the highest sound fidelity.

Really big and still efficient and not weigh a ton. Paul has long said he prefers the sound of Class AB amplifiers to that of Class D but recently PS has launched some Class D hybrids. So AB makes sense when you need to get loud and you dont need 100 perfection just 99 perfection.

Class A amps have greater output than Class AB amps. Sound quality of Class D vs Class AB amps. You write your sentence and feed it in and class D makes bigger versions of your letters but it.

It eliminates the cut-off by ensuring that some current flows during idle and throughout the transition from one side of the push-pull to the other. If two EL84 output tubes in a Class A design may produce only 10 watts of output power then the same two tubes in a Class AB design might produce 50 watts. Class D amplifiers are models of efficiency but with a loss of detail and fidelity Class B amplifiers generally introduce some crossover distortion but move away from Class D G and Hs extreme non-linearity.

In electronic terms Class AB push-pull is like two asymmetrically biased amplifiers that mirror image each. Class B design is a little more efficient but full of distortion. I think D are just more entery efficient but dont match sound quality of.

Im very surprised that BASH amplifiers arent more common these days. I disagree with your first post Matt especially the comment about D sounding like tubes. Class D design has the highest efficiency but isnt quite as.

I currently have a pair of Schiit gasp. As a result real world efficiency tilts further in their favor. My first thought is that a class D would have less audible harmonics.

Has class D switching amplifiers come of age enough yet to seriously challenge the superior sound of class AB amplifiers. Midrange was better but lower midrange was leaner had to change speaker cables. Never have I thought that.

This is a disadvantage to some musicians who are looking for good clean tone at. Give me a class D GK head that has the biamp the front panel controls of a 7001001 DI and biamp and a serperate rails switch that simulates the sound of a RB series pushed. Pros for class AB.

Between a well designed class AB amp Outlaw Aragon Perreaux Cinepro Rotel AB International and a well designed class D amp Crown XLS2500 I dont hear very much difference at all or at least any differences Ive heard could most likely be contributed to the comparison not being blind. Class AB design offers power efficiency and good sound. The better Class D amps Ive heard get the tone right but nothing about the presentation is correct.

By doing so class AB amplifiers can keep a higher level of audio fidelity closer to class A amplifiers while staying cooler and more efficient like a class B. Drool avvie Wicked G Mystic Michael and 3 others like this. In Class AB you have actual audio coming through the entire amp where in D its converted to a PWM signal at some point.

Whats his opinion now. The second problem of Class-D is that the last thing the signal sees before it reaches the loudspeaker is the filter. Then you have class D.

Class AB amplifiers may introduce some crossover distortion but they get closer to the ideal of Class A for most of its operating regime. Lows were tighter while highs initially sounded less extended but they just sound different - cymbals are less splashy.
