SF Guarneri Homage or SF Extrema?

I owned the Extremas and heard the Guarneri on several occassions. Both speakers are excellent, with the Extrema speaking with a richer, fuller tone and the Guarneri a little brighter amd more transparent. The Extrema sounds "big", can play much louder, has explosive dynamics and great extension on the bottom. With the right amp it can produce quite some "punch", something that the Guarneri cannot do (Guarneri's bass is quite articulate but doesn't reach near as low). Both speakers have very refined and luxurious treble and they both image very well.

I can see Guarneri excel with small scale jazz and classical and the Extrema with rock and large scale orchestral music (although it can sound pretty refined with small scale music too).
The Guarner is easier to drive, whereas with the Extrema you'll need at least 200 watts of solid state or 100 watts of good tube amplification. Your Ayre amp is great, but it may not be enough.

Guarneri much better look than Extrema. Also easier to place. Own short coming is to have a music subwoofer to fill the inadequate bass.

The Extremas are much better. There fuller and richer sounding. The Extremas make anything else I ever listened to pale into the far distance. They have an impact that will stop your pacemaker. A realism that is scary, soundstaging that is so holographic. The bass is nut-tight. I also agree, I dont think your V5 is enough power on the Extremas. The Extremas need power and lots of it.
My friend is using Meridian 557 amps bridged on the Extremas, where are 800 watts. That is an awesome combo.

The Sonus Faber Extrema speakers are the most incredible and accurate speaker. I've owned dozens of Hi-end speakers in the past 30-yrs. But the Extrema's remain in my reference listening system.

Beautiful sound and workmanship at it's best.

*The Extrema's are a great Italian work of art.

I would go for the Guarneri. There are a bunch of great speakers that have super dynamics and play loud, including the excellent Extremas. However I believe the Guarneri are in a league by themselves. The Guarneri are magic in the midrange, arguably the most important part of any sound replication or performance. The Extremas and Guarneri are both works of art, so I would say it's a tie in that department. Bass is relative thing, the Extremas do have better extension. But if it bothered me that much I would get a Rel subwoofer and have all the bottom end I would ever need plus retain the Guarneri midrange and sophistication. Good luck.
