Building on the success of Aucharm Grounding Boxes, QA has embark on prototyping and thus developed its own version with the aim of improving the structural build as well as further enhancing the quality and effect of the ground boxes offered.
QA Premium Audio Grounding Box, at a little over 2kg, weighs heavier than Aucharm XL Grounding Box. Not only is that containing more ‘ingredient’ for a more effective grounding, we have found out this can be an optimal mass to be used on most regular equipment. The choice of using a cube-shaped box is also a deliberate one – it looks balanced, non-obtrusive and can be easily placed on any side as required per anyone’s equipment arrangement. It is small in footprint and hence it may look even sleeker than Aucharm XL Grounding Box.
Internally, pure copper sheets at 0.05mm thickness lined the walls of the box. This creates a ‘live’, contained box acting like a mini Earth for the noises to be grounded and the surround conductivity also maximises the contact with the contents inside the box.
The main contact, however, has to come from the central rod of the speaker binding post where another thicker, folded sheet of pure copper as well as dozens strands of 4N purity silver wires are attached. Basically the aim is to get all the unwanted noise and interference current from the audio equipment it is attached to and get them to contact with the box contents as much as possible.
This ingredients mix has always been the guarded secret for almost all such ground boxes commercially available. But every box will have a different mixture. QA Premium Audio Grounding Box uses a vast selection of mineral mix in various granular sizes to balance the compacting nature together with the grounding strength from the assortment. About 2kg in total weight, there is no scrimping at all in the use of these minerals, all of which are natural.
We would have shaken and mixed evenly the contents on our end during our production, hence any vigorous shaking on customer’s end is not strictly necessary. Breaking in of this grounding box will be beneficial, but the positive effect can already be quite immediately evident straight on first use. We always recommend to connect ground boxes at the earliest possible components of the audio chain because that can help to result in a cleaner signal path as much as possible right from the beginning. Hence connecting to CDP, DAC, Turntable, pre amps and power strip/conditioner have the most impact of the setup.
From our observation, the more transparent background allows instruments to be better lifted to the foreground, where the boominess in the bottom frequency above sub-bass often due to noise is now better suppressed. One can expect a cleaner and faster bass. There is also better spaciousness from the sense of air some recordings may possess which gives vocal music an added touch of intimacy.
QA has included the multipurpose crocodile-clip cable (50cm, additional S$5 for every 50cm extension.) for your wide variety of connections. We recommend the use of specific RCA to Banana plug cable if the intention is to connect the ground box to spare RCA ports instead using the crocodile clip to clip on the RCA ports.
