Joe,
I've had the same pre-amp for going on 13 years. I have not had one bit of a problem. I can't believe how good that little thing sounds. Unlike you, however, I'm not really fond of the "passive" mode. But I'm glad that you like it. I can't believe Adcom stopped making the unit. Find yourself a reputable tech and put him/her on standby. If it ever needs servicing, it should not be a major deal. If you live in the Hudson Valley area, let me know. I can recommend a good technician.
In the meantime, keep enjoying that little giant killer!
