Did anyone experience Audio Prism's Ground Control


Fellow Audiogoner's

I wonder if anyone has any input on Ground Control spade versions? I am curious about the impact of these pigtails on your system's overall sound?

I also have their quiteline filter (4pack) installed in my HT room and they have helped lower the overall noise floor.

I got a pair installed on my Duevel Bella Lunas driven by a Wavac EC300B. The effect is not subtle: much increased air and transparency in the treble (particularly noticeable on splashing cymbals and the like) as we as more articulation and speed in the bass. Weird but effective
I actually have the GC's on my amplifier (an AudioPrizm Debut with new OPT's and power supply mods) on my Sony CD/SACD player and my Planet 10 Fonken boxes with EnABL'd Fostex 127 eN drivers installed. The amplifier GC's provided about half as much back side of the wave information retention as the GC's on the speakers. The CD player GC retained the high frequency information as music, rather than the rather harsh, grainy, unmusical edge to sound that the unit came with. Not proselytizing here (much anyway) but I suspect some folks are wondering about uses in other locations and these have been my results. I do also have them in my transformer, stepped, isolated attenuator preamp, but most folks don't have one of these.

I am not a dealer. I am just the idiot with the idea. Music Direct and I think one other (I will check on this) are dealers. I don't even make the parts, though I do design and build high level audio transformers and provide EnABL patterns for free use to DIYer's and also as a source for those who want the benefits but don't want to learn to do the process. The Ground Control is just a spin off of R&D on cables, to obtain as sonically invisible a cable as possible, to allow me to further refine the transformer designs for audio reproduction.

AudioPrisim is an entirely separate entity and the GC's are being marketed and manufactured by them. This is actually the only way they could have been brought to market, as I do not have the contacts in the business they do. They are in fact the people who drove the commercialization of the idea, so without them, there would be no Ground Control.
