Anyone know anything about NEC Renaissance Speaks

Thanks for looking. I have a pair of NEC Renaissance floor standing loudspeakers model RS-100. I am looking for someone to tell me about what I have. I bought as dealer demos back in 1985 and I am looking to upgrade but it would be nice to know what opinions are out there about what I have. They have been very good to me but the upgrade itch is bad. Thanks
That long ago and that brand (don't they make computer monitors?), I would think you would have a huge number of upgrade options.
Thanks Tarsando...exactly...too many options!
I have a new solid state int amp and new tuner with tube output and looking to get a really good SACD player with a tube output but am very uncertian about the speaker pairing.
Have any suggestions.
