As I understand it, bubbles come from shipping and mine has gotten
better with age and rubbing in circular motions. I, too, was

something in the instructions or on the website about that, but I don't
have time to dig at the moment.
Make certain you keep the thing moist in the humidor, that is the big
drawback, IMHO, but the second Sigma was almost totally useless--much
less sensitive than the first (now dead) unit. Andrew Wedman who used to
be at Universal in Europe complained that the Sigma was much too slow
for their production work.
So far, the new Arnold has been doing well for me, though I did use
Kyread when I was looking at digital recordings as I think it has higher
