Mixed…all my Audio Research gear (phono, line stage, amp) is in silver as I’m a traditionalist. My SimAudio Moon gear is black but I do strongly prefer their black and silver designs.
My source component rack is on my side wall with only my amp between the speakers in sight during listening. Therefore, I would consider an Audio Research amplifier with a black face plate. Although, when truly focused during listening, eyes are closed anyhow, so what difference does it make?
