My response to your question isn't about the quality of Bryston gear or service, but digital playback equipment in general. I've been buying CD and SACD players and DACs since the first days of the digital revolution. I've had equipment at price levels from $500 to more than $5000 per unit. Denon, Cambridge Audio, Assemblage, Marantz, Luxman, Arcam, and others I can't recall at the moment. Both my experiences and those of friends lead me to think that the most troublesome parts of CD players are the displays and the laser read assemblies and the rate of failure may not have anything to do with the price of the unit. Probably part of the reason is because most CD players made use parts from sub contractors and a manufacturer cannot control a sub contractor's quality control issues.
Unfortunately, I don't think there is any manufacturer you can depend on to make a CD player that is CERTAIN to last more than five years. There's a certain failure rate for parts and no manufacturer is immune from parts failures. The unfortunate reality is that if one wants to enjoy high end audio with a high price tag, one has to be willing to gamble that your equipment will fail and you may lose your money. You may lose your "investment" if the manufacturer goes out of business, no longer can get repair parts, changes distributors in your country, or you decide to sell and your equipment is no longer in favor with the current tastes of buyers out there.
Like yourself, I have gotten tired of constantly replacing prematurely dead CD players that were expensive for my budget. I've had several rather expensive players die after just a few years only to find that they couldn't be repaired because some part the manufacturer sub contracted is no longer available. For that reason, I spent more than I'v ever spent in the past and bought a Luxman SACD/CD player in large part because of their reputation for durability and in-house manufacturing of many components. Time will tell if that was money well spent.
