Sonus Faber Guarneri vs Guarneri Memento

Both GH and GM uses Audio Technology midwoofer. Audio Technology is a new name of Skanning, so effectively they use similar drivers. Audio Technology might not make their own cones, instead they only make the coils, spider, and magnets and that's why Daveyf mistakenly think GM midwoofer is sourced from Dynaudio. I am 100% sure it's Audio Technology. How do I know? I have a spare driver.

I have owned just about every single Sonus Faber made including EA1, EA2, Cremona Auditor, Cremona, Extrema, Amati Homage, GH, GM, and some of the lower lines. To say Dynaudio T-330D is the best tweeter ever made indicates you have not heard what newer technology has to offer. I have lived with Extrema for years where T-330D was considered very well executed there. I had Extrema, Amati Homage, and GM all in the same room once and everyone walked away ranking Extrema lowest because of its top end deficiency. Lack of air, lack of micro dynamic, and lack of extension.

Scanspeak Revelator, even the old 9900 in Amati Homage was considered more detail than Esotar T-330D. The new Revelator is simply in a different league, by a long mile. When I owned GH, people liked the sound because it was coherent and smooth. Now I own GM, people LOVE the sound because it offer everything GH has to offer and much much more. I will even put Scanspeak Revelator tweeter up against ribbon, I also own Aerial 20T which has one of the best ribbon tweeter in the business, it's a modified Raven R-2 that cost $1k each.

GH reminds me of Roger LS3/5A, pleasant to listen to but you should know its limitation. GM reminds me of a BMW M3, an all purpose sports car that you can live on the edge.

Semi,
I have heard the Scanspeak Revelator, the Raven ribbon, the Accuton tweeter, the Accapella Plasma Ion tweeters, the Maggie ribbons and others. IMHO, and frankly in many other 'philes opinions, the Esotars are still up there with the best. Why not ask Bobby at Merlin why he still uses them? Comparing the GH to the GM I still believe that the cabinet, the x-over, the drivers and the bi-wire ability of the GH is superior to the GM.
Sorry, but when we 'AB'ed the GH with the GM, the magic of the GH was not present. Not just my opinion but our entire audio club that evening.
Comparing the GH to the LS3/5A would seem to indicate that you have not heard the LS3/5A's or maybe the GH's. The LS3/5A's are good speakers but have a definitive BBC coloration ( boxy somewhat woody sound), which I do not think that Italian speakers of any brand exhibit..:0)

Daveyf, of course you are entitled to your opinion and I am entitled to mine. Like you, the whole audiophile circle here thinks GM is significantly better than GH by a mile.

As of which tweeter is the best, there is no end to that debates. I have spoken to Bobby because I owned Merlin VSM before, reason why he is still using antique Esotar T-330D is he believes in 2-way design and he can't move up to the new Esotar2 which has better extension at the expense of not going as low like Esotar1. On top, Dynaudio is not selling the Esotar2 to anyone, so Bobby is stuck with his old design which he has tried to perfect for 10+ years. Can you imagine Bobby switching tweeter now and start this whole VSM, VSM SE, VSM M, VSM MM, VSM MMe evolution all over again?

I have lived with Esotar1 for 7 years, from SF EA1, Extrema, Merlin VSM, and Dynaudio C5, I think I know a thing or two about Esotar. in fact, I was like you who used to defend Esotar until I open my mind and start listening to other designs. If you love Esotar so much, you should get a pair of Dyn C5 to hear what Esotar can really do.

Daveyf & Flg2001, you should be able to find Guarneri driver source easily on Stereophile reviews, both models were reviewed before and drive details were clearly mentioned.

Semi,
MF at Stereophile reviewed the GM's in Vol 30 #8.
In it MF says the GH's use Scanspeak woofers, which as we both know they don't. He also says he hasn't heard the GH's so of course he cannot compare the two models ( fair enough).
The 6" Audiotechnology unit in the GH's was custom made for SF... apparently true for the GM's also. Now I have one question.... Do you believe that the ability to bi-wire is of value?
Also, so we are all clear on this point, I do NOT feel that the GM and the GH's are vastly different; there is a very similar family resemblance between the two speakers ( they are both SF's after all) and both are excellent speakers, both are mini-monitors however and because of this cannot compete against larger floorstanders with the ability to move air.(Bass response if frankly the weak point of both designs). I just feel the GH's have a certain magical midrange that the GM's seem to lack. That is IMHO.
