From an appearance perspective, the nicest piece of equipment I have owned was a JBL SA-660 integrated amplifier. It was an amazing example of beautiful industrial design. Wish I still had it.
What's the best and/or favorite piece of equipment you've owned? And do you still own it?
My favorite piece(s) are (and I still own them) the Martin Logan Ethos lousdpeakers and Soudsmith Paua cartridge. As far as speakers go, electrostats are my favorite and will replace them with another set of electrostats. I'm currently eyeing MUR Audio SP1's. These two pieces make my rig sound great.
