Class A or Class D solid-state amplifiers (modern designs)


Hey guys.

 

Class A is supposedly superior. Something to do with a conduction angle of 360 degrees...so the entire signal gets processed in one go without crossover distortion.

But in terms of sound quality (subjective enjoyment) is there a benefit to Class A? Can class D provide the same level of enjoyment?

 

The dealer I’m talking to says that really nice Class A amplifiers are designed for "reference quality" meaning completely true to the real life performance.

 

Let’s compare and contrast. Which one is technically better?

 

In other words, could you have equal technical performance and quality in a Class D amp?

This is the only current amplifier that I have heard that left that feeling of that is special with me. Not sure what class it is but I know to me it was special! With the continuous increase in use of the internet there are very few brick and mortar stores left around here where top end equipment can be heard but this set of amplifier s I heard and really loved. 

 

 

Re comment above by atmasphere I can understand one of the reasons why my class A/B monoblocs sound so good - they use zero feedback and run very high into class A (400w each at idle). BAT VK655SE's.

You aren’t going to find better measured performance than a pair of Hypex NC400 Monoblocks.

Perhaps forget about 'technical performance' and configuration.  By 'quality' I presume OP means sound quality.

That's what all of us are looking for, but it cannot be an absolute - each of us has different tastes in sound reproduction.

So I suggest OP  just goes and listens to a range of amps of many configurations and takes the ones he likes best.

Check out the new Topping PA5 Class D amp. $349! Clips at 110wpc@8ohms with 1% distortion. Uses advanced circuitry and has an input level control. Ranks just below the Benchmark AHB2 in SINAD at 1/10 the price!
