While I liked the sound quality of the amp fairly well, it developed a problem where one channel began distorting then went dead.  This normally would not be an issue although the short warranty had expired. Even so I shipped it back to the vendor and awaited a repair estimate. The estimate was over $450.  They told me it could not be repaired because of all the silicone that was holding the components in the pipe.   They had to make a new amp.  They did say they could reuse the power supply and this is why it was not quite full price.   As much...
