Thank you for the reply. Sounds like you have a good combination with all the various devices and cables that you own.
+1 for this “The effect that I experienced can only be chalked up to "settling in" after shipping -- a different concept than "burn-in" in my vocabulary”
My system was in storage for nearly a year after we moved. Man, after I fired it up the first time in the new house, the sound was atrocious. I knew what the system could do; wide stereo image, layering, holographic sound field with clarity of vocals and instruments. It took about 2 days of being powered up and used before all came into focus again. This settling in period I just chalk up to warm up, albeit somewhat extended, but due to the devices and cables already being burned in, it is so easy to discern and hear the difference a day makes when all comes to life again. Afterwards (initial warm up after long pause in use) it is only an hour for me to obtain excellent sound due mostly to the 80 plus tubes warming up.
