It seems you are ready to reboot, based on your comments. Where do you live? The wilson Sabrina is sublime, makes sophia 3’s sound kindof broken to my ears. YMMV. There is a preowned paid of sabrinas at audio arts in new york presently. 1st rate dealer, Gideon.
As for Duettes and Duette 2’s, Ive owned both. The Duette 2 is quite a bit more refined but it should be for the price leap. There is a pair of Duette 2’s pre owned for a crazy good price.
what equipment are you using presently?
