They did not and I have not pursued them. Fortunately I found the problem a couple of months ago. It turns out to be a problem with one channel of my Lindos audio test set which happens to be the one I use all the time. For some reason it has developed an initially intermittent but gradually worsening dop in response both at HF and LF no matter which brand of transformer is used. It is not clear at this stage if it is the driver or receiver end that is at fault. Anyway, I now use the sweep function in REW via a USB interface and nicely flat frequency responses have returned.
