Like you, I’m trying to get to a point where I’m “done”. And by done I mean that I have arrived at a point where I could easily live with what I have a decade or so from now when I retire. My amp , speakers, and speaker cables were the first to get to “done”. Surely I can do better, but I don’t hear these doing any harm and I‘be been delighted with what I’m hearing from them.
Getting the digital side to “done” has taken awhile but I think I’m finally almost there. An EtherRegen when played a key role in this as it helped to reduce harm that was being done to the music by my network. But to my surprise, the ER did much more than that by helping to allow me to hear deeper into recordings. Powering an ER with a Super3 was another surprise. This may have made as much of an improvement as the ER itself. I should also mention that a Sonore opticalModule feeding the ER a run of fiber also played a big part in making my network less harmful. I realize that many folks are going way beyond this by deploying multiple audiophile switches on after the other. Abyss Man does this, for example. I’m satisfied enough with my network now that I’m inclined to say that I’m “done” as far as the network goes.
