@tramey I'm familiar with the trade-off between a lighter tone/timbre and more forward sound vs warmer sound with more body and more laid back soundstage. In fact, just last night I was going back and forth between two sets of outputs on my preamp - one with Jupiter copper caps, and the other with an RTX/Teflon combo caps. That was very much the tradeoff I was hearing last night. RTX/Teflon had a cleaner/clearer sound, but only because it was emphasizing the attack and not the full body of instruments. This also made the sound more forward, versus more relaxed soundstage with the Jupiter caps and a warmer body/tone to instruments.
What I heard with the Furutech wall plate was a bit different. Yes, the lighter tone/body, but a LESS forward sound. I attribute this to further reducing distortion which was causing sounds to be a bit more bloated than they should be. Greater refinement of the sound, but with a shift in tone/body. But it did leave me wanting some of that tone/body back.
One thing that helped dramatically afterward was upgrading to the Ultrarendu from the Microrendu. That upgrade brought back the body to a large degree while also increasing refinement and detail further. So, I think the wall plate was helping me to hear some tizzy distortions from my source or other aspects of my system to a greater degree than before.
I'm a believer in the NCF products for sure - I haven't heard an application yet where they didn't increase resolution and refinement of the system. The question is whether that's always a good synergy, because it may require upgrades in other parts of your system to achieve a new balance at a new level of refinement. Only you can be the judge whether you've got the cojones and wallet to go further down the rabbit hole.
