@62truck , I think my tweaks fall into the category of, it works for me and may or may not work in your scenario as they are dependent on a variety of variables. But for what it’s worth, I switched from using Herbie’s Tenderfeet under my components to Herbie’s Giant Fat Dots, inserted under stock component feet. These made small incremental improvements and I liked the sound better. But what really transformed everything beyond belief is when I installed the dots under my Innuos PhoenixUSB reclocker. The level of stability, resolution, and overall noise free sound was astounding.
The other thing I changed was plugging my Diablo directly into my second, unused, 20A dedicated circuit. I had tried this years back and it sounded better plugged into my Torus RM20. But I have new cabling, components and speakers now, and now my system sounds far better with the Diablo straight to the wall. More natural mids and overall more free and flowing; easier to listen to.
