A few days ago I assembled my Quadraspire Q4 table which I have had for about 14 years.
However, I have realized that my Nac 202 does not rest on all four feet on the top shelf, but only on three: can this be a problem at the expense of sound? If so, what do you advise me to do?
My Q4 has 19mm columns and flatfoot: do you think replacing the flatfoot with the spikes and related floor protectors from Quadraspire can help refine the sound?
The spikes and floor protectors definitely improve things. They add the all important decoupling without which, much if the benefit of a rack is lost.
The 202 not resting on all feet is not right. Even if the Q4 is done up wonky, the shelves will be flat. Have you tried using a different shelf? If it is not resting on all 4 feet on another shelf then it means the 202 is wonky, not the rack.
It’s worth checking that the shelves are level and that the legs are not done up too tightly. It may be that one of the shelves is bending because the legs are too tight, or it may be warped, so do check.
The shims mentioned above are only relevant for Naim boxes with metal feet. The 202 has rubber feet so you do not need to worry about shims.
I trivially solved the problem by raising a foot of the Q4, I did not remember that it was so sensitive … and I did not even remember that Quadraspire supplied the spikes in addition to the flatfeet that I inserted … well, I just have to buy some floor protectors. … and a spirit level (ion case…).
The kit with metal feet were levelled up (before packing) on a piece of perfectly flat aluminium plate. To do I this, thin aluminium shims would be used where necessary, because the metal feet offered no tolerance, so had to be exact. Of course other surfaces, such as wood, glass etc… were never guaranteed perfectly flat, so Naim offered spare shins that could be supplied to the installing dealer to ensure no rocking.
With the normal feet with rubber inserts, unless a shelf is particularly uneven, the rubber should have enough tolerance to ensure no rocking.
