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.

My Audiomodded Sony SCD333ES 5 disc SACD player/changer. Still makes lovely music to this day, going on 16 years now!  Absolutely terrific sound, and without any harshness associated with CD's.  Really shines with SACD's.
