I have a pair of SP100s, which I purchased around 2005. Here’s a link to pictures that I posted of the entire system about 18 months ago. I was fortunate to buy them as a dealer demo and paid a reasonable price. I agree that the most recent versions of the big Spendors (and Harbeths) are reaching eye-watering levels, as seems to be the case with many flagship designs.
Other contenders at time were Dynaudio Contour 3.0 and Audio Physic Tempo. All three were wonderful, but the Spendors won me (and my wife) over with their special ability to reproduce instrumental timbre.
An extravagance that I’ve indulged since this photo taken was to add a stereo pair of REL S/510 subs. While the SP100s, with their 12-inch woofers, are by no means bass shy, it’s still difficult for passive speakers to really plumb the depths of low bass. No regrets about this decision.
