AudioPrism Ground Control Spade Reference, 1 pr. Positive reviews. $200 MSRP

Selling for $75.00

Simple but effective tweak

Original Price: $200.00


There are a fair amount of write up on AudioPrism’s Ground Control Spade Reference that I shall leave it to you to Google it and read up about it. I would just tell you to take this and hook one to each negative terminal on the back of your speakers and then sit back enjoy a “refreshing” take on your music. If you can find another pair, you can further enhance the music by connecting that pair to the negative speaker terminals on your amp (although the previous owner of this pair said the improvements are more subtle).

Cosmetically, the pair looks good. They are the earlier version with the rubber outer sheath instead of the later designs which had fabric. One owner since new. Unit will be securely packed for safe shipping.
