I'm a wireless addict. I once had an X-Wire, but I sold it to get some other gear. Now I miss it. They are rare and hard to find. So then the Sennheiser folks bought the patent rights (or something like that) and they make the Digital 1000, which sucked and then they release the 1092GTR Digital 1000. I haven't heard any reviews of the new unit, but the coplaints of the Digital 1000 was that it squashed the tone. They might have bought the recipe, but their cookin' wasn't no where near Grandma's!! So, what wireless units are you folks using that might compare or that give you the best clarity in the low end? The Samson Concert IV is the ONE unit that I's accept as a sub, but lo and behold, that one too is in the archives as it is no longer in production. What's a junkie to do to get his wireless fix???
