“I admire the engineering skills and craftsmanship almost as much as I admire the sound of the Upgraded Graaf. It takes great skill knowledge and knowhow to do an upgrade on a piece of equipment. You can go to far and totally destroy the sound you loved so much.

Having Knowledge and understanding of component’s being replaced. How they will work to improve the sound/ listening pleasure of your item rather than destroy it is a must.

The Graaf is beautiful in every way. From the engineering to the sound.
No more humming. Just clean, clear, precise. Same old Graaf sound that I love. But better.
