In an upper end TESLA System (comprised of Apex IC source to pre, Precision Reference IC pre to power with Apex SC going to the speakers) most systems benefit from at least one Precision AC in the mix. In my system it's on the digital clock with a Hologram D on the one box CD player and Hologram A's on my Amp and Pre.
I designed TESLA power cords as a system by creating individual synergies for each component instead of building a "one size fits all" power cord which would yield satisfactory results in most systems at the expense of truly exceptional performance for experienced audiophiles willing to put in the extra time and effort. Try finding one spice or ingredient that works well in all recipes- basically you end up with salt- in the TESLA Series that (salt) is the TRICON geometry and we do have cables based solely on that geometry (Precision Reference IC, Magnetic Tricon and Tricon Analog) for all other models we combine Tricon with other geometries which have there place in different systems. Obviously if one size fit all we would only sell pure Tricon models.
Balance comes when you take time to compare different combinations of TESLA cables in your system and in so doing achieve synergy.
