I recently purchased a pre-owned Classé Sigma Amp2 (class D) in mint condition to pair with my B&W 802D and am really enjoying it. I got a great deal ($1,300 - MSRP was $3,500) and it tested favorably in all reviews it was featured in. Anybody else have experience with it?
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?
