I recently installed the Farad power supplies on my Dave.
Really transformational. I will of course try the fuse upgrades next. I am on the hunt for and m scaler now.
The retrofit is very easy and completely reversible if need be.
Chord Dave and lInear power supply
I had been using Chord Dave and Mscaler for 3 years.
I installed linear power supply by Farad which cost me around 3k Euros including three separate power supplies.
Wow it is worth every penny.
I get more clear separation of each instrument with more tuneful bass.
Also slight sibilance is gone.
It is Dave +. after modification.
If you own Dave, you had better try it.
The installation is rather handy.
You need to follow instruction.
