Introduction:
Thank you for purchasing the Pass Labs XP-32 line stage, we trust it will entice you
to re-discover your favorite recordings and explore new musical delights.
At Pass Laboratories we do not change products or offer a new model unless we
believe the changes offer significant improvements over the previous version. As a
result we typically experience products with a seven to eight year production run.
We are constantly working on and listening to new circuits and components,
increasing our knowledge and seeking better sound and enhanced product reliability.
Over time we find enhancements worthy of putting into production and significant
enough to warrant a change in design. That time has come for the XP-32.
The new design uses uses double shielded low noise torroids in a true dual mono
topology for the gain channels and another transformer, linear power supply
dedicated to the control architecture. The use of three fully independent power-
supplies in the control chassis results in dramatically lower radiated noise and far
better THD+Noise figures in the gain stages. Residual circuit noise becomes
paramount at low signal levels. By going to extreme lengths to lower noise we enjoy
better resolution and dynamics in the music.
In the two gain chassis we continue to use our favorite NOS Toshibas but with larger
and higher biased output stages in a topology very similar to that used in the Pass
Labs “Flagship” Xs Preamp
The larger output stages bring practicality to much longer and multiple cable runs,
both balanced and single ended and gives us the advantage of simplifying our single
ended output circuitry while simultaneously increasing performance.
The volume conrol is a single stage topology, it features greater range, 0.5dB volume
steps while being quieter and more dynamic. Overall this makes for a quieter
and more versatile control center for your music system. The XP-32 measures
spectacularly well but more importantly it stands out sonically
