    I bought this amplifier, I tried it with cassette player and CD and it produced sound perfectly clear and beautiful. I connected 2 speakers of 5 watts and they worked flawlessly. I highly recommend it for anyone who wants it for relaxing music in a room, neither big nor small, it is perfect. I give it a 10 out of 10 easily for purchase
