My memory from the first couple of RMAF's was Danny and Gary brought LS-9's during one or two of those first 2 or 3 years, and those crazy big blue tube amps Gary built. Frankly, those were the best speakers Danny ever brought to RMAF, including the Super-7's IMHO. The LS-9's did not need a sub, and they had plenty of mid-bass energy, and plenty of grunt down low. They were huge, but that system was one of the best I heard anywhere, and at any price. The LS-6's were just a smaller version, but still very good, and more manageable in the real world. I've not heard any of the new speakers in the X, NX, LGK, or the Old School Series, but did build the Desktop Mini with my Granddaughter. I still think the LS-9's are one of the best I have ever heard at producing fun, accurate, and engaging music. Plus the scale is just massive.
Just my useless $.02 worth,
