But, I recently upgraded my desktop speakers to the Micca RB42s. The amp does power the speakers, and it sounds good, but the line-out really is not designed to power speakers, especially low impedance Miccas, so the volume is at the max position for reasonable output… which of course isn’t close to where HD600s need to be for most listening.
I did try the Topping MX-3, but didn’t like the sound signature on the speaker output – too bright. Headphones was okay, but the matrix was better.
What would you recommend, adding as few components as possible, since I like the headphone sound on the Matrix. I’m open to replacing the whole lot if that’s what needs to happen. The key thing is that I need a switch to alternate from speaker to headphone out. No unplugging the headphones. Which seems to rule out the more popular options on the market at the moment.
