Stay grounded

i got the Chinese boxes (Aliexpress:https://www.aliexpress.com/snapshot/0.html?orderId=8147827966369582&productId=4000164972611&edm_click_module=order_detail&tracelog=rowan&rowan_id1=outfordeliveryV2_1_en_US_2022-04-04&rowan_msg_id=9582814782796635$d9939e06f0f84affaf309b3e43c2b5a4&ck=in_edm_other) and attached them to the negative posts on my Duevel Bella Lunas. Significant opening out of the sound stage in both depth and width, much clearer deep bass and an all around clearer rendering of recordings

On a separate note I converted an old power cable into a grounding only connection and attached it to one of the negative binding posts on my Wavac EC300b amp with similar positive but altogether smaller effect.

Speaker grounding is highly recommended (be careful, though, your amp should be single ended, you otherwise risk shorting it)

Amp, dac and Etherregen are grounded to the common ground via the earth point of the power conditioner. As this didn‘t work for the server, I experimented with the AR device and liked the result.

Any experiences with grounding boxes on negative terminals of speakers out there?

@lalitk,

pls give us your experience. I‘ll try out some Chinese boxes and give feedback

??? It’s in my post
