Update after few years !! Latest are Emm XDS1v2, Gryphon Antileon Signature Monos, and Update of Dartzeel latest updates, version C pre V2 and E power. 30T worth of Music on NAS and Aurender Player with Shunyata Electrical Filters. Of course Speakers are ProAc 100D NOS. Will connect Dartzeel Power to Dynaudio 25 years special soon!
I also own a pair of Guarneri Memento. In my main system, Guarneri sounds absolutely superb. All the typical audiophile adjectives can be applied and better yet they convey music like nothing else. But moving my Guarneri to a less system and all of sudden it sounds average at best. So mating Guarneri with Dartzeel is not an overkill, Guarneri demands the best front end and performance will continue to improve with every upgrade in the front end.
If you can afford to pull Guarneri far away from the rear wall, they will reward you with huge soundstage and imaging.
I have heard both Strad and Savoy in a small room, Savoy does have more bass definition and either speaker should go to a very large room. You can try stuffing the rear port of Strad to reduce bass output, eliminate rear wall interaction, and improve bass definition.
