My Aiwa AD F-770 three head cassette deck. 38 years and still going strong with nothing more than a belt change. Also, my Marantz st6000 tuner. These are the only things remaining from past systems.
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.
