Good discussion going here. Picked up a nice pair of 1000M's last summer and have auditioned them with some of my different receivers and amps. Solid state and tube. Usually they are hooked up to a Mac 110z pre and 2125 amp. Get the best of both worlds; tube sound with solid state power. That said they sound fantastic driven by my 800C, hardly a powerhouse or my Scott LK-72B again same power tubes 7591A. Now powered by my Sherwood S5000 with 7189 power tubes the combo is OK but the Sherwood is sublime with my other speakers. Recently restored a big Marantz 2330 and have it hooked up to the 1000's at the moment and it's is nothing short of amazing most of the time. A crap recording will sound like crap like Sam says but this is what they were designed to do. The Marantz is very clean and crisp with gobs of power and it really wakes up the bass and those big mids. Easy to get lost in the music and I find myself listening for subtle sounds in the background you maybe did not hear before. On a side note I have replaced the cheap stock connectors with good binding posts and at the same time replaced the thin stock wire from the terminals to the crossover with good 14ga speaker wire. This made a big difference in the bass both in quanity and quality. Easy update to undertake and the stock terminals do not get damaged so they could be put back if one chose to.
