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.
