ARC REF 6 upgraded by ARC.

I don’t believe you have to send it in until they’re ready for it

 they don’t want to be storing a bunch of private gear

Congrats on your new system 🙂👍 those components are what I would consider the end of the upgrade ladder. I hope your reality is as good as my imagination. 

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. 

@gregdude Thank you very much. And definitely this is  what I would consider also the end of the upgrade ladder for me as well. I also hope my reality is as good as my imagination as well 👍👊💪

Your point of contact will be Greg Christensen. He's an affable young fellow. 

Greg said that since the scamdemic everybody is pulling their old gear out of storage and wanting it fixed. Apparently it deteriorates in storage. ie corrosion in the pots, cap bleed, etc. 

You will send an email for a place in the que, get an acknowledgement back, then you will get an email about 7 months later telling you you're getting close (30-ish days) to the ship-in time bit "don't ship it now".  About 45-60 days later you will be told to ship- when, where and how. 

That was my experience since August 2022 for an SP-15 refresh. Meanwhile you can enjoy your Ref 6 and fall in love with old recordings you rediscover anew. 

The 750s and an Anniversary preamp are my dream system. I just need to finish the kitchen remodel first before my anticipated upgrade. The anticipation is as much or more fun than the event. :)
