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.

My gear -
Krell Showcase Pre-Amp / Processor
B&W 803s and 804s (rear)
Marantz UD8004

Audience Au24e speaker/interconnects.

Still for $150 bucks plus shipping it still sounds like a "maybe/iffy" product.

Well did you also state this???

"How large is the effect of these devices? More than I hear from the Isoclean fuses but not as much as an interconnect or speaker cable upgrade. However, what the GC devices do may be unattainable from a cable upgrade. I have rarely, if ever heard this combination of virtues from a cable upgrade."

Yes. My statement merely tries to convey their relative value. This is where your own decision making must come into play. It seems that you do not want to try them. There is nothing wrong with that.

Mesh50, I really wanted to demo them. But unlike for you a professional reviewer the Manufacturer does not support demos. There response to me was to purchase them and if I did not think they did anything try to get a refund.
I have bought items on those terms only to have a real hassle getting my money back

I suppose it is easy to paint all manufacturers with the same brush, when you've had a bad experience. I've read many such tales of woe on Audio Asylum and elsewhere. I think both Audio Prism and Music Direct are very reputable companies and Music Direct would happily refund you. Of course, it is your money and your decision.

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
