Synergistic Research active shielding question

These are in a bedroom system and the bright blue LEDs are, well, bright! I was unplugging the MPCs at night (at the power conditioner, not at the cable) but have read that the cables don't like to be disturbed, even plugging and unplugging the MPCs and for max performance, leave them plugged in 24/7.

So I took a bit of electrical tape and wrapped where the LED is.

Does anyone see any issues with this? Will it affect the active shielding or the sound any? I'm new to these cables so I don't know.

In the last day they seem to have lost a lot of bass... but then last night I was at an outdoor concert so everything still sounds strange like there is cotton in my ears lol. (yes I know... should have worn earplugs!)
