Audio Research was purchased a few years ago in a highly leveraged deal by a private investor. Increased interest rates caused him to have to sell the business. It was sold to a deep pockets committed company that is already into high end audio. ARC is not in jeopardy of going out of business. They maintain the same dedication to producing new products and servicing old ones as they always have. Which is why they have a stockroom full of parts to service former products.
I highly recommend the ARC Ref CD9SE if you can find one. It is the best CD player / DAC that I have heard. It bested the $22K Berkeley Alpha DAC in my system and a number of others. It brings the rhythm a pace and midrange bloom of real music, as well as the detail and realism.. Through the player I can get the exact same fidelity by CD player and through streaming of the same recording. Frequently, I can get better quality through high def files streamed through Qobuz since I have an exceptional streamer..
