Very fond of a pair of LXmini's I DIY'd last year - inspiring the sale of Tekton DI w/factory upgrade, and they outshine the ML's, B&W's and GE's (floor-standers still have in the stable). Others just can't compete - they all just sound like speakers to me now, while LXmini's disappear and sound real. However, I have not heard many other speakers that might compare favorably in this arena (Spatial, Project, GR-R, etc.). LXmini's do require subs for full-range. ML e-stats share some likeness, but have such a narrow sweet spot. I'll probably always keep a pair of LXmini's (these, or future builds).
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.
