Wayne,Could you please email me the plans for the Pi 2 towers?
This morning I had to move some old stuff that had been sitting in my basement and found a pair of 1 Pi's that I built probably 8 years ago. At the time I had used them with a 2A3 based amp and they sounded pretty good but I decided soon after that SE amps weren't my thing and I moved on to other equipment and speakers.
So I dust them off and hook them up to my cheap Panasonic receiver that I use in a small HT system. Even without stands these things sound great with this system. The added efficiency over the Magneplanars that were on this system really contributed to a more viceral and dynamic sound that is really fun to listen to . My wife even likes the sound better. I know comparing bass reflex/horn loudspeakers to 'planars is about as different as it gets, but in this room and with this amp the Pi's work so much better, that I think its time to put the planars up for sale and build a new pair of Pi's.
Thanks,
