I would look at this very differently. If I was wanted any ARC equipment I would order it immediately. Before possible price increases, when you know they are making incredibly high quality equipment. 
 

I have been involved in integrating purchased companies for much of my career. I believe the buyer knows the quality and history of the company and is going to want to preserve that legacy while determining how to fix the cash flow problems. Unlikely there will be any impact to manufacturing quality or designs for months… maybe longer. Although, price increases like the recent increase in upgrade prices are certainly possible.

 

This is a great window to purchase stuff. A good friend just ordered a preamp and amp. Good move. Shipment is a week out.

Acora Acoustics is a 3 million dollar company. I don't see it unless they have some some partner

How might this effect those who already have ARC equipment? I own a preamp and am waiting delivery on a power amp. Both used.

No effect. I bought my first Audio Research component in 1980 (used). I used it for an over a decade, and a friend of mine still has it and is using it… over 40 years later.
