"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.
Recently had JS Audio do a stage 2 upgrade on my 17 year old A300 integrated amplifier and the results are very impressive. Initially it sounded much more dynamic with far more detail and control and as it has run in continues to get better and better. It has brought to life a 3 way speaker I was contemplating selling, they sound so much better, the transformation is quite staggering. I find myself listening to music at a lower volume than previously as the detail is much more apparent. John has been very helpful and informative and also talked through options for an obsolescence issue i had with my Linn CD Player and would definitely recommend him.
MF X-Ray 24bit CD full upgrade - worth every penny!
My CD player had developed a fault that was tripping the mains. I discovered JS Audio repairs by searching for my fault, and gave John a ring. It is such a good CD player I opted for the full refurb/upgrade.
Now I’ve been playing the renewed player for a couple of months, all I can say is ‘holy detail and separation, Batman!’
Clarity, dynamics, separation, staging are all just off the scale improved.
Really critical listening to much loved CD’s has revealed detail and production quality that was previously hidden.
If anything goes wrong with any of my music gear and hifi, I will be back to JS audio repair for the excellent service, support and mind blowing impact on sound.
Excellent service and upgrade.
What can I say, this (previously tired) old amp sounds much better than I can ever remember. Better control at the bottom end, and the overall clarity and projection is stunning. I know John was impressed with the upgrade suffice to say I’m amazed at the transformation. I can’t recommend Johns upgrade and repair service highly enough, and my friend will be dropping in his Claymore Incatec for an upgrade as ASAP!
