Just got my Epifani 4 x 10 running it with Eden WT-800 and I have a feeling that my rafter is about to cave in. After trying this cabinet, I am an Epifani believer, and I got it up a flight of stairs! Luckily my stairs are carpeted, so I just roll the darn up the stairs. E string that shakes some serious booty! Mmm, I feel kinda nauseous too after 2 or 3 hours.
