What is the "extra" maintenance that you've done?
To answer your question - both.
In brief, my thoughts are:
1) it stands to reason that a machine with electronic/software-driven sequences and so many moving parts will require maintenance over time,
2) some of those moving parts will fail and/or require replacement,
3) it's extremely irksome that the design of the original ADS RCM (and to a certain extent the Pro) does not have better quality parts and is not of a design that allows easy (by user or in-country distributor) maintenance or replacement of parts,
4) I'm frustrated by the need for a repair/replacement solution 3 years into a $4000 "premium class" purchase exacerbated by the appearance that these failures are not rare.
I signed up for a premium RCM whose marketing has proven more robust than the machine itself.
That said...when it works, it's an effective, convenient machine that has added enjoyment to my record collection.
