The mains transformer being the very heart of any high quality power supply, the TPX2 is graced with TWO of the superb AST laminated transformers - one for each regulator module. With two quite separate secondary circuits, designed specifically for low external noise and an absence of spurious harmonics, this is the lowest noise power supply system we have ever measured.
What does all this mean? Well, unless the sine wave from the mains supply is transformed without aberrations, the capacitor banks and subsequent regulator systems - however technically clever - will never be able to remove the final traces of any mains borne aberrations. Result? small detail veiling with an untidy treble performance, detracting hugely from the enjoyment of the music.
After being rectified by some fast recovery diodes for lower spurious effects, the resulting DC (Direct Current), is passed into the first large storage capacitor. From this area, the DC is further smoothed by high current inductors for the removal of the final vestiges of nastiness from the supply lines and passed into the second high quality storage capacitor.
Having ensured we have the finest raw material - the rectified DC supply - we are now free to begin to put all that power to work beginning with a fairly conventional voltage controlled primary regulator followed by a series of storage capacitors selected for ripple rejection along with a speed of delivery necessary to portray those fast transients without sonic losses.
