Massdrop x THX AAA™ 789 Linear Amplifier - Impressions Thread
I am using Z1R,A2000Z,Z7,TH-X00,SRH-1840. They sound weird on my 789. The mid-range (vocal) image is excessively wide and big.I can feel a huge mouth in a close range. In some tracks it covered over 80 degrees field of view. This sound signature is special. And none review I seen mention it...- chenszhanx
