Hey Doc,
Yes, the Solovox speakers do take a lot of patience waiting for them to come to life. However, you will be greatly rewarded as you log several more hundred hours of playing time. I agree that your upstream components are a great fit for the speakers and I wish you many more years of enjoyment with the speakers.
Not only did the cats work as living, breathing damping material, they were also inter-changeable between the speakers and not so dependent to which speaker they slept in, but they did have their own preferences with loading into the left or right side :-)
