If you have a Sonus Faber dealer nearby ask them when they will have the new Lumina II in for demo ($1200/pair).
I owned Castle Isis (20+ years ago) purchased from their distributer in Niagara Falls and have also listened to Castle Pembroke floor-standers (sp?) plus the original and 2nd version of the Richmond.
I replaced the Isis with Renaud Twins MkII around 2002 and then switched to flea watt tube amps and wide band single drivers (which I still use).
On the cheap (if you can find them) you would probably like the Richmond or Richmond II.
I'm considering switching to SS for the living room setup and am interested in the Lumina II's based upon listening to a few "good" Youtube demos.
A local dealer (I'm in Los Angeles) either has or will have them in stock shortly per a blurb on their website.
Never been a SF fan in the past, but liked the YT sound of their new inexpensive stand mount.
One YT video/demo compared them to 2 other speakers.
