Unsound, that sounds very sound, and one of the benefits go higher efficiency speakers
Class A to XX Watts
I've only used pure Class A (Aleph J), never an amp that started out in Class A for the first few watts only. Wouldn't the transition out of Class A be audible? Seems to me that if it is then that would be a bad thing. If it isn't audible, then why would anyone design it that way to begin with (marketing?)?
