As the owner of an A/V company for the past 20 years, we constantly look for good products Made in the USA rather than go with the crowds. This Rolls amplifier we discovered years ago, is the industry standard for our installations. Very well made, simple, small package, and fits our bill in many, many installations. I have lost count of how many of these we have installed. Never a dimes bit of trouble, plus you are supporting jobs in Salt Lake City, Utah, when you purchase this product.
