@jdm11 , SF Olympica series are basically successor of former Cremona line and are priced accordingly, somewhere in the middle of SF range. Olympica 3' price was around 12t eur in Europe when it was launched, very close to the Guarneri Evolution (around 15t eur, with the stands) which was part of the same generation of speakers (in terms of date of production). Aldo some can object to the very notion of 'monitor' speakers (to be equal or better than standmount) it is generally considered among SF fans that Guarneri is 'better' product, or at least was made with that intention.The US importer of SF obviously thinks that way, as he has put hefty price on GE, making it some 10t usd more expensive than O3 (in europe that difference is perhaps 3t) Anyway, if speaking only about the speakers and if you can find them similarly priced, Guarneri is more refined product of higher quality. It will have less bass (which in smaller rooms might be an advantage), but 'more' of everything else. Depending on music that you listen (jazz or classical for example), you should enjoy it more. It will 'demand' higher quality electronics to show its best, must be said. At the end, it all depends how demanding you are. Olympica 3 is a great allrounder, but if you wish something more, or something 'special', I would look at other solutions, including ones from Franco Serblin's new company, that I have mentioned before. Last, but not least, imho all SF benefits from amps that have more power. They can work with tube amps, but are not build with intention to be paired with them.
