Amplifier for Sonus Faber Guarneri Homage

I used mccormack dna dlx for some time, after AR vt100 mk2, and now gamut d200 mk3- the best I heard, I think that SF guanier sound sweet with a lot of amplifiers, but gamut is the best I heard, I do not think tubes are better with SF guarniere( many others thinks that tube are friend of SFG) they are only diferent, and to me gamut has more bass , sweet medios, and soft silky hihgs.I think SF guarniere is a fantastic speaker.

I tested YBA 1, YBA integrated, AR VSi55, Copland, Shanling stp80, unison s2, unison unico i and others.
The best sounding system I found was the Graaf 13.5B II tube preamp with Graaf GM20 otl ocl (a little expensive, but worth it), this system is very accurate, quiet, smooth realistic vocals, strings, bass strings. It is magical sounding (no transformers, no capacitors) this is about as direct as it gets. If your room is large, buy the GM200 you will appreciate the extra watts, I am listening at low volumes nearfield in a 10x11 office. I have ordered the Graaf GM200 for another system, this should be amazing.
Graaf is made in Modena Italy near Ferrari, they use the best materials in there hand built instruments. I had 4 audiophiles with me when I first hooked up this amp and they told me that they had never heard an amp so transparent and smooth, after a few hours of course the ss guys when against the tube guys as usual, but even the ss guys were impressed with the delicacy of female vocals and strings. If I listened to the system louder I would run the GM20 in mono (I hear they are spectacular). It runs hot, but that is a small price to pay for that warm tube sound. My Guarneri's sing with this wonderful amp. Another collectible just like the Guarneri's.

I'm actually running my Guarneri's with the MF Tri-Vista and have been very pleased over the last 2 years.

This replaced my combo of ARC LS22 pre with Mark Levinson ML3 power amp - a combo that I kept for years without hearing anything making me feel the need to change.
When I moved to Japan, I needed to replace them with something more compact (the ML is a monster !) and decided one of the better integrateds was the way to go.

I tested the offerings from Jeff Rowland, Levinson, Krell Chord, Gryphon and none had the right combination of liquidity and control of the MF.
This was a surprise as I was very much predisposed towards the ML !!

After many months of auditioning amps for the Guarneri's I have found the most incredible sounding amp for these wonderful speakers. It is the Graaf GM200, output transformerless and output capacitorless. 32 tubes on the output stage and eight tubes handle other various functions. 200 watts per channel. The most musically realistic sounding amp ever. With this amp you peer deeply into the recordings innermost musical structure. Wide deep soundstage, bass is layered, brass is full and rich, voices are hauntingly real. The details are marvelous.
If you own a pair of Guarneri's you must hear this amp.
