Any Spendor sp 1/2 owner or former here ?

...bought a pair of them, new. The rest of the system is a Naim CD5 and a Cary integrated SLI-80 Signature in triode mode almost all the time that shouldn't be more than a year old each. Basic Chord interconnect and bi-wiring. Found two use Sound Anchor stands too, tune to that model they say.
If you will, I'd like to learn from you things like how long in your experience did it take for them to sound their best ('break in period' I think you say in English ?); what did you discover that made them sound better : positioning, room treatment, cables (maybe)... ; how long did you keep them ; or anything you may think of.
For myself I find them already quite involving ; intellectually they are quite satisfying also, as they effortlessly reveal every musical line in anything I fed them but I am more into emotions.
I wish they would sound a bit fuller and hopefully they will ; for the moment they're not the warmest of the world. Although they reveal the athmosphere of the recording they don't bring it my house yet even with eyes closed.

Forgive my limitations in English.
Waiting to share impressions and knowledge with you.
