In reality there's no competition between the two, if you have the room and the expertise to set them up properly, the X-1s are unbeatable! Watt/Puppy 7s are very fine speakers too and even if they're not a match for the X-1 you will get better results from them in a smaller room. Please note that both speakers are very revealing and would show up any weakness in your system. I know that the Grand Slamms have been accused of being sterile and lean but that's simply not true, most of the systems I heard them in were setup poorly and with harsh sounding ss electronics. You'll grow to love the X-1s if you know what you're doing.
