After 25 years, I still have my Bryston 4B NRB, along with my Audio Research LS3 preamp. I enjoy listening for several hours every day and I have no plans to replace either one. The cost of what I would consider a marked improvement is more than I can shell out right now.
After 21 years, the Bryston did develop an issue. I took it to my dealer, Audio Advice, and it was shipped to Bryson. They repaired it at no charge, even though it was a year past the warranty period, and even paid the freight back. That is customer service.
