Summary: Great Purchase. Great Seller!! Great piece to add to your bose entertainment system. I went ahead and bought this piece to have sound in the patio and inside the house. YOu can add two recievers to this amp. IT will help in the end for you to prevent your from over powering your speakers..
Summary: What can you say its a Bose. If the product was an issue, Bose would back it up. The SA-2 amplifier is a great all around unit that is used with a majority of all Bose Lifestyle Systems. I am running 3 SA-2 and 1 SA-3 in my system and have not had any troubles with any of the units.
