Like @jafant said gear matching is the key and i can tell you guys that the Diablo 300 is really not a good match for Thiels, the tweeters will let you know.
Even with Cardas cabling it didn't tame the treble so i got fed up and sold my Diablo 300.
If you want Danish better look at Vitus awsome match with Thiels.
Just my 2 cents.
I think i'm going to order the Isoacoustics Gaia ll footers for my 3.7s, will let you guys know how that work.
I already put many of them under my electronics and the result is spectacular.
