ARC Ref 3 preamp - updates or concerns


I am considering a used Ref 3. Are there any updates in its lifecycle or potential issues to look out for on these units? I will be pairing with a Ref 110 and also considering a new LS27, though the Ref 3 can be had for about $1k less than new LS27. Any feedback or advice is much appreciated.

Your best bet is to contact ARC with the serial number and ask them if there were any updates made after it's production.

From what I've read there were some changes made over it's production run.

I had A problem with my Ref3, it wasn't a big deal, one of the tube socket's had to be changed at the two year mark, ( purchased it new ) , the repair was done locally. The hour meter can be reset, so be careful if your looking for a used one.
