It is a secret. Pro gear is elusive.
Being that Sherbourn was primarily used in professional installations, it very likely the end users do not know enough about their equipment to do a review, or compare to other brands. On the other hand you may find in this community some who are capable of such a review and do own the equipment. Perhaps post a thread asking for feedback? This thread does not address that question, and therefore lacks the content you are looking for.
I own three PA5-200's and I find them very powerful, clean, and well made. They provide a good deal of excitement during movies and concerts. The price was just right for us, and the 10 year warranty is remarkable.
