  • Upgraded silver internal wiring.
£225 for stepped attenuator upgrade only
£260 for stepped attenuator and internal wiring upgrade

We can also upgrade the P50 B-Grade units for you - just a few now left in stock.

I can live with the noise between resistors, but I understand those that opt for a cost effective upgrade.

Are we talking a sq upgrade as well?

Clarity and separation. Subtle...but you won't want to go back.

I cannot find drawings and dimensions of P80 - as it is very old model - would have to see it inside to be certain SA will fit.
Nothing to see here...

The P80 is about the same size as a P50. Way bigger than my P90SA

Great to see new update being rolled out. Well done guys.

I have the P50SA.... is this upgrade worthwhile for me, yes I do get narked with the volume crackles now and again. :o If so is it the same price as above? I assumed it would be.

Or would I be better just jumping to a P90

If you don't need dual mono, stick with the 50SA.

The upgrade will give you silent and smooth operation and a subtle lift in clarity and separation.

Yes, price is the same.

All the preamp ugrades will be dispatched by the end of this week. More than 20 units being upgraded, in total. Several went last week and here's today's batch.
