i brought him a B&W DB1 amp for him to take a look. He asked to give him 2 weeks and he'll follow up with me. More than 2 weeks went by so I decided to give him a call. He simply told me my amp wasn't repairable etc. I asked him to explain and he refused to citing that since he wasn't gonna fix it so he rather not comment on it. His house was full of old audio and video equipment hence I bet he was really busy. The amp powers on and I could make adjustments, it just doesn't play any sound. He could have just told me from the start that he didn't have time to fix it and not make up excuses along with the bs that my amp wasn't fixable. He was quite self-centered and rude in our first meeting when I dropped it off at his house. I would not recommend this person, Thanh
