How close are Horch House copies to the original master tapes?

We believe that they’re as close as it’s possible to get – not simply to the master tape in its current condition, but to that master tape’s original condition.  Thanks to our detailed 'soft refurbishing’ process, our master tape copies could, in a sense, now be considered as better than the current originals because they’ve been lovingly restored to deliver the same sound quality that the originals had on the day they were first recorded.
