I purchased a pair new in 1980; still use them in my second system, driven by a QUAD 606-II power amp. I could not even think about parting with them now. They still look great and sound excellent. Lots of dynamic range, tight bass and crystal clear mid/upper with fantastic transient response. Of course there are better speakers available (I love my Nautilus 801s), but for the money and longevity, you can't beat the NS1000Ms.

Let me know if you have or have listened to these speakers. I have owned a pair for the past 2-3 months and they are really nice. I own a pair of Pinnacle Aerogels that don't have quite the detail or quickness in the midrange and tweeter. I have not heard speakers this nice under $2-2,500. Really unbelievable!
