Available now...

Upgrade your NVA P90 passive preamplifier to MKII P90SA specification:

  • Upgraded silver internal wiring.
£400 for stepped attenuator upgrade only
£470 for stepped attenuator and internal wiring upgrade

Improved clarity and separation.

Order the upgrades here: https://www.nvahifi.co.uk/preamplifiers ... tion-etgx3

Upgrades are non-returnable / non-refundable. We will return your original attenuator(s) to you with your upgraded item (or dispose of, at your request).

Would an upgrade of P90SA to the MkII, with wiring, bring about a SQ improvement as well as the elimination of the crackle I get when turning one of the knobs? My system is very responsive to subtle upgrades as I recently discovered when buying the MCRU PS for my DAC.
I set a course just east of Lyra
And northwest of Pegasus
Flew into the light of Deneb

Yes.

A subtle but worthwhile improvement in clarity and separation.

Silent and smooth operation...

Seems like it will be well worthwhile. As I will not be home much until November it will be in a couple of months time.
