I am going to chime in. I have a separate thread where I was asking about the newer Classe class D. It has really impressed me so far. Does not sound like my previous experience with class d. Sounds like a very musical and accurate class a/b but with a ton of power on tap for tight and pronounced mid bass. I was very skeptical with a $4k msrp. I am very happy. However Classe tuned this amp, they did a really good job. Renewed my faith in class d. I will keep it for quite some time.
