Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems My journey with Meridian (and Shunyata, AQVOX etc)

I recently bought an ex-demo Denali and wanted to experiment with grounding given the reported benefits (both here and elsewhere). I followed a suggestion made to me a while ago to start with the easiest first - grounding via rca outputs on the 818 and speakers (albeit using a different grounding system to the Denali). The Improvement in sq was immediately obvious - completely took me aback. Much greater precision and energy to the music, far more involving.

Turns out though that I was using Chassis grounding on the Denali for signal grounding, which should be done separately. So tried grounding the speakers instead but heard no difference. Odd! (I couldn’t bring myself to try the 818.)

Reinstated the rca > chassi ground system and again it sounds great! I’m not hearing any hum or any other obvious drawbacks. I’m assuming unless someone tells me otherwise, that it is okay to leave the signal ground as it is?

I will try the chassis ground again at some point, but I do have some questions. I notice that the screws on the speakers are covered in black paint and did what I could to sand the inner head of the screw to provide a connection. I take it that in my case I should use one of the corner-most screws which hold the bottom plate where the power input is located? I wonder if there would be any risk in removing one of the screws completely to remove the paint? Unplugged first, of course. I was also wondering which screw on the 818 would be sensible to use, and again whether it could be safely removed to enable cleaning?

I suppose the general takeaway here is that if you have not experimented with grounding your system, it’s well worth doing.
