I have nothing against the RS stuff at all because they did have some really neat stuff that was affordable for a great many people in that era (including me). I always loved to go visit the local RS in my town as a friend of mine's parents owned one. But there is no way I could ever choose something of the likes of a "comparable model" pair of JBL, Altecs, Klipsch, Polk, Infinity, etc, etc, etc over a pair of Mach any revision model or anything else they had built by some other company. Again, no offense because I've owned some of the RS gear in the "good" era and my first real TT was a LAB-400 (I think it was). But, again, given that both were comparably priced (give or take $100) I'd rather have speakers that came from a company that designed, engineered AND manufactured them. But those Mach's were a great party speaker....that's for sure. Until the L100's or HPM-100's showed up.
But I sure do miss perusing the RS stores back then. Especially growing up in a smaller town at the time.
