Monoblocks for Sonus Faber Guarneri ?

On second thought, are you the owner of the Graafs mentioned in another recent thread? If so, why not keep those for the Guarneri & spare yourself the trouble (& the money) of change? If not, do consider them, as well as Tenor (75 should do), Jadis (80 upwards) OR -- ss -- YBA passion (stereo is OK), S-Line Kraft 250 (stereo, one of the most enjoyable matches). BUT you'd have to consider eschewing the balanced connection...

Many other choices are sure to surface: I'm just relating my limited experience with your speakers (later model). Cheers

My Guarneri's are from 2001, and I'm not the owner of the Graafs.
Monoblocks, because my speakercables (Kharma Grand Ref) are only 1 meter long.....
Do you feel the LAMM M1.1 blocks are overkill for these speakers ?

I've used three different monoblocks on my Guarneri's. The first was a pair of Bryston 7B ST's, which were a bit dry with the Guarneir's and definitely overkill in the power dept. I then switched to Aronov 9100 monoblocks with KT99 output tubes (about 130 watts), and these kept me VERY happy for a couple of years. The Aronov's had very good control of the bass, a reasonably tubey midrange, and nicely extended highs. Then came the CJ Premier 8 in XS configuration (about 120 watts per side of EL-34 triode power). Night and day. By far the best sound I've gotten out of the G's, with a much more realistic, palpable image, awesome transient attack and decay, etc, etc. CJ monoblocks are a good match with the G's, but they don't do balanced (I use custom terminated AQ cables with XLR's on the preamp end and RCA's to the amps), and they have one set of binding posts. However, my speaker cables are set up for internal biwiring, so no a problem. Another option is to have a set of jumpers made out of the same high quality speaker cables and ditch the pretty but sonically crappy SF jumpers. This works well also

Peter -- no, I don't think the 1.1's are overkill. I find the G's very seductive speakers, possibly the best SF has produced (within the Gs' frequency response range) -- but also difficult to drive to "perfection", i.e. to get the last ounce of their capabilities out of them.
For example, the ss choices I refer to above are all apparent overkill (esp. for the physical size of the speakers).
These are the result of a "tournament" we conducted with a friend (owner of the G's, also 2001 pair). We were trying out amps (such, as were made available to us AND he could afford/payment terms were acceptable), looking for a SS that could approach/emulate the musicality AND the perceived accuracy of a loaned CAT combo (tube) we used as "reference". We listened exclusively to symphonic music, lieder, and some opera.

the mac 602 drives sf's effortlessly and hits some bass notes that your not going to here with a lot of highend monoblocks...smooth tubelike midrange too.
