@bhazard I already have Takstar ts 671 and Pro 80. If I order HD 5500 or HD 6000 will there be other sound characteristic difference? If yes, better 5500 or 6000? I listen mostly to vocals.
I have the TS-671 & Takstar Pro 80 (Gemini label) & HD6000.
I really only use the Gemini HSR-1000 (Takstar Pro 80), of the three.
