I just received my L/C/R Sierras on March 10th, and I am impatiently awaiting the arrival of my D15SE.
So far the Sierras have greatly exceeded my expectations, and they are just sitting on top of some old HTIB speakers right now. To my surprise I've gone from 90% home theater/10% gaming to 100% music since they arrived. I can't wait for the weekend to get here so I can really sit back and enjoy these amazing speakers.
So it's good to be here, I'm super stoked, and I'm looking forward to many years of good sound
