Sonus Faber Guarneri's

The Guarneri's are something very special especially for a second system. They will need an amp with more oomph then 8 Watts. Depending on how loud you like to listen and room size, I wouldn't give them less than 50 tube-watts and preferably more (86.5dB/W/m). The Guarneris like space from the side and front walls to really sing. And need maybe 9-10 feet from the listening position to gell. They sit taller than most monitor speakers (50"), so a 9 foot ceiling height is better than the typical 8 foot height (again even higher ceilings are better). In short, small rooms are out and nearfield listening is less than ideal for these speakers. The older 8 panel versions should be much harder to locate, but some have said they're better than the newer version. They also do not go much below about 42 hertz so you'll need a subwoofer (REL STENTOR?)I have also heard that some Guarneris a few years back have had finish problems (a white film underneath the varnish)in more humid parts of the world. You are looking at a very musical monitor with one of the best midranges ever! Good Luck in your search.

Thank you very much Dovetail!

To add a few notes to Dovetail's and second some suggestions.
{Ref to recent pair with a "factory tweaked" esotar tweet (haven't quite grasped exactly what they did to it)}.

Very musical is the motto, one of the best sounds I have experienced. It's also commendably fast (i.e. timing is top-notch).
Power: that's a difficult one. We first tried these speakers with a number of medium-sized amps, and got stumped (the esotar sounded too loud, or the instruments were lacking in volume, the voices were clear but "angelic" i.e. disembodied...).
To give an indication, we started driving them well and getting beautiful music at Passion stereo / Symphonic Line Kraft /CAT JL (whatever) stereo levels. Another amp we tried was the KR Antares tube (good driving capabilities) -- but, no cigar. Unfortunately, these were the available amps (i.e. no big bat, cary, arc... etc).
The cables used were bearlabs -- consistent in earmarking differences between the amps. We also had Nordost spm's (IC & speaker) on hand, but they seemed to invariably excacerbate the tweet frequencies at the expense of the rest of the spectrum, so we gave up on them.
We listened to classical, leider (mono & stereo) and symphonic music.

Placement: as above, with listening position about 3ft away from the back wall and toe in focusing behind the listening position.

If there's anything youneed & I know, don't hesitate.
