Review on Bellari Audio PP532 Passive Preamplifier by Dominique Garrett

Bought this to switch between the dedicated DACs and Focusrite Scarlet (and yes I know this is a DAC too). I wanted to use a dedicated DAC for music and Focusrite to record and play the guitar through a PC. PP532 is connected to a topping headphone amplifier, which in turn is connected to headphones or powered speakers. It works fine for this purpose and I can't tell if there's any degradation in signal or audio. The case is well complex (fairly thick metal), and the volume knobs and inputs switch okay. I think they are plastic but they don't seem flimsy. I don't hear any noise when switching inputs. I don't hear any noise when changing the volume, but for my purposes (since I mainly use it as a switch) I just keep it at full power. The red color is nice but not as red as my topping headphone amp or Focusrite Scarlet (which go really well together). I would buy this again.
