Wadia 861: internal switches


Apologies if this is posted elesewhere.

Does anybody have details of the internal switch settings in the Wadia 861? (i.e. that control the volume).

I am currently listening to the 861 at 55 and would like to increase this to 75+.

Any information gratefully received.

Paul.

Here's what Wadia says:

All switches open = 0 dB / 4.25 Vrms
Switch one closed = -6dB / 2.13 Vrms
Switch two closed = -12dB / 1 Vrms
Switch three closed = -18 dB / 0.5 Vrms
Switch four closed = -24 dB / .25 Vrms

The factory setting is 2.13 Vrms
