For a frame of reference I had the Magneplanar mg 1.7i's before getting the DI's and had the Legacy Audio Focus SE's at the same time. The DI's had pretty much everything the Maggie's but added a lot more dynamic slam and much better bass. The DI's had a much more realistic soundstage also, one more in scale with the music than the larger than life soundstage of the Maggie's. The DI's and Focus SE's were more similar than dissimilar but again the DI's had more dynamic slam. All three speakers are wonderful and I'm not knocking any of them, I just preferred the Di's. For me the DI's presented the most realism and dynamics while still at least equaling the others in most other sonic attributes.
I listen to a wide array of music with jazz and female vocalists being my favorites. And yeah, every now and then I like to revisit my youth and rock out to the likes of ELP, Metallica, Bowie.....oh anything from the 70's or 80's. Mostly it's the likes of Holly Cole, Patricia Barber, Sarah Jarosz, Rickie Lee Jones, Cowboy Junkies, Sharon Jones and the Dap Kings, McCoy Tyner and Keith Jarrett that I listen to. The DI's with my Decware Torii tube amp and PS Audio Perfectwaves provide beautiful music with all.
Are they perfect? Nothing is but I've found no fault with them yet.
