@edcyn Vocalists. Any genre. Do the male voices suffer from a buzzy midrange distortion? Or do they sound rich, clear and authentically human? Are the sibilants spitty or hashy?
+1
Vocals are the most challenging. We hear human voices every day for a reference. Do they sound natural in your system? (Allowing for a slight touch of reverb.)
Big +1.
Vocal has to be the most challenging music to play on a stereo. Vocals in any audio system, regardless of cost, are far back away and empty void. I visited many audio shows hoping ultra expensive audio systems might be close to the original music. But nothing was really even similar to the real music. So, I made Wavetouch audio system that produces human voice sounds like the human voice. https://www.youtube.com/watch?v=XaBy9CcGoTE
