“Took the TARA Labs Prime M1 speaker cables out of the box and heard a difference right away. Bass weight was there, so was a great soundstage. I use B&W speakers and the combination is really great. Thanks!”
–TARA Labs Customer

“I went and purchased TARA Labs Prime M1 audio cables on the advice of a friend without listening to them. I was extremely pleased to their sound. Detailed, clear, with sounding articulate. I has replaced my Nordost cables for just that reason. Really great cables, thanks!”
–TARA Labs Customer

“I hooked up a TARA Labs Prime between my CJ pre-amp and amp and could immediately hear the difference. Clean, precise, detailed with a real full mid-range. Saving up my money to be able to get a 0.8 or maybe even a Zero (though I doubt my wife would ever let me do that)!"
–TARA Labs Customer "Kevin M."
