As for the sound I did a Led Zeppelin "In My Time Of Dying" test... joyfull and all I was looking for, foot tapping by the firsts seconds! The drum kit sounded more alive than ever, the kick, the soundstage is far faaaaaaar better than my old B&Ws, I love them already! Wo needs anything else with all that life and body & soul pleasure? I don't! If can tune finely for a bit of clarity and it will be heaven! This is... yes I'll do that stupid joke ;) Stairway to Heaven! We did not feel the need of trying the B&Ws back, just to package them and put them away!
(maybe it can't be seen on my room's picture but the are slanting by few degrees backward)
