The velcro on my SBLs fell off, finally. I tried different sorts of Velcro, including heavy duty and none were the same or worked properly in gripping the covers. Velcro UK were very helpful and after sending a photo of the original stuff told me that the correct, double-hook Velcro is MVA8. It is 25mm wide so needs cutting in half, but that looks like what Naim do as well. Velcro kindly sent a sample and it is the exact same stuff that Naim use.
Apols if everybody already knows this.
