Re Welwyn Nick?

The 808.3 Anniversary features a LPS. Previous versions have SMPS.
Can the standard 808.3 version simply be upgraded with LPS?
The 818 has a LPS therefore is ID41 really better than ID40?

Consensus of published opinion suggests that the power supply maybe more influential to achieved SQ.

Just my enquisitive nature.
