With system changes, such a different presentation, when I actually listen.
Had Jack Johnson Brushfire Fairytales playing. Something I know very well from daily listening for a couple of months in 2004 (a rough spot in my marriage).
Macbook to Halide Bridge to Bushmaster II/Audience AU24SX RCAs to Perreaux to ATC SCM19v2. Merlin Scorpio power cable, Merlin Scorpio speaker cables, Akiko Triple AC Power Enhancer.
Tweaks recently added: iFi AC iPurifier, Audioquest Jitterbug, Shumann Resonator Chatres SE, XLR Noise Stopper input caps, Coherent Supercapped Power Supply (into Beresford Bushmaster II), SR Red fuse, Akiko Audio Fuse Box tuning chip, 2 x Akiko Audio Universal tuning sticks, RCA input shorting plugs, Mad Scientist Nitro power cable.
What I noticed, was how rich the music sounded. Base, just floats. Seems like it is no longer restrained. Drums? Striking (pun not intended). Voices, clear and smooth. Noise floor? To my ears, almost disappeared.
Still waiting on iFi USB Silencer, Russ Andrews 'The Silencer', MCRU Mains Filtration plug, Shumann power supply, Graphene Contact Enhancer, and probably another Mad Scientist Nitro power cable.

I'm looking at adding the ifi AC purifier and Jitterbug to my system - did you find them both individually worthwhile?
Very much so with the iFi AC iPurifier; it's worthwhile. Reversed the polarity yesterday on the cable into my plugboard, which made the music even smoother. Was very quiet. Found mine for US$70 on eBay.
I need to check with the Jitterbug. Do some critical listening, to see if it makes a difference.
The grounding plugs didn't on my amp, but on checking with Perreaux, they said their amplifier inputs on the R200i switch to ground when not in use, so there would be no benefit using them. "When an input is not selected, it is pulled to ground automatically. If you measure the impedance of an unselected input it will be around 220 ohms; there is a single resistor in line before each relay." So, although they are in the amp; effectively just dust plugs.
