ARC REF 6 upgraded by ARC.

Yes but wait times are in months. You should email them. The upgrade is around $3K and well worth the money in terms of improved detail and soundstage.

Basically you are in queue waiting for return authorization. Once you get that you have 30d to get unit to them and they start when received. Customer pays shipping and ARC prefers original packing. They want tubes but out of unit in original packing with the unit. No remote, manual, power cord. 

I knew there was a reason I stopped reading and posting on these forums. Silly of me to return.
