In My Humble Opinion (IMHO):
The new Rubi “T” High Performance Umbilical Cords provide a SIGNIFICANT improvement in sound reproduction for ANY REX (i.e. REX, REX 2, or REX 3) preamplifier by Balanced Audio Technology. Rubi is our new mid-level collection of cables and cords. “T” stands for transformational, terrific, more “teeth”, and/or Tyrannosaurus. J
ANY REX preamplifier, with the Rubi T High Performance Umbilical Cords, will reach a NEW, HIGHER PLATEAU of sound reproduction and SIGNIFICANTLY outperform ANY REX preamplifier with the stock umbilical cords. For example, a 1st generation REX preamplifier with the new Rubi T High Performance Umbilical Cords SIGNIFICANTLY outperforms a REX 3 preamplifier with the stock umbilical cords.
