I didn't get to buy from TbazAudio Tony Shahbaz because he is incompetent. Turned out, he sells what he doesn't have in his possession. In my case, pictures were not of the actual amplifier. Tony doesn't know what he sells. When we discussed technical details, he was saying nonsense or wrong numbers, etc. And he is so arrogant to admit that he is wrong, so he started blaming me that I don't know a thing... Also, other folks concur my experience with Tony Shahbaz. They said they purchased something from him and left negative feedback, but it was removed by Agon. Thus, he has good feedback.
