Sorry the URL didn't go to the product I wanted. Check out the Turbo-X or Turbo-1. The website says:

The Turbo 1 and Turbo X increase the pre-amp level being delivered to the amplifiers. Increasing pre-amp level signal helps to better balance your system and allows you to get more "juice" out of your amplifiers.Signal to noise ratio of 96 dB for high quality sound.

BY THE WAY: I DO NOT WORK FOR OR HAVE ANY AFFILIATION WITH PAC. I just like their unique products
