Like Mick W and Daryl Z, I'm using a Freya+ and running XLR with MiniGan mono 5's. Even if I was unable to qualitatively describe the improvements I'm hearing, I know that something has happened in terms of musical quality, compared to my previous system configuration, because I find myself listening longer than I ever have. Morning listening sessions regularly extend for 20-25 minutes longer than I ever listened before I placed the MiniGans into service. Additionally, I end sessions listening at higher volumes because the presentation is so clean and impressive. For me that's really the tell that something has changed for the better. This, about 3 months into the MiniGans.
One other thing: For those who suffer with bothersome (and aren't they always) sibilants or spitichiness, it seems the footers one uses for the MiniGans can impact tonal quality. Although I was never obsessive about footers under various gear, I have tried various footers with the MiniGans and found vibrapods to be the most pleasing, i.e., preserving detail and clarity but also diminishing (it seems) sibilants, spitchiness and, as important, an occasional hard or glaring leading edge seemingly limited to human voice. Although I think burning in the units was, by far, the most critical to reducing glare and edge, it all adds up.
