I want to thank everyone who took the time to respond to my original post. Also, I want to respond to a number of their suggestions and observations. First, both of my amplifiers were sent back to Krell in 2017 for complete restorations. Second, my Silver Eclipse speaker cables have had 300+ hours of listening level music played through them at this time, so maybe additional hours will help. Third, my Revel Ultimas all have aluminum-alloy dome tweeters and aluminum midrange woofers; aluminum is known to have a tendency to be somewhat bright and even at times a bit harsh sounding. My prior Transparent cables might have mitigated that brightness with their own "mellowness", though that is just a supposition on my part.
I live a long, long way away from any high-end audio dealer. It is not really practical for me to audition a number of candidate amplifiers, should I eventually conclude that would enjoy my listening more if I had amplifiers that complemented these speaker cables (which continue to impress me nearly daily). For that reason, I am eager to receive the thoughts, insights, and recommendations of other Audio Aficionado participants.
