As an owner of speakers that are no longer manufactured, I can tell you it’s no fun walking on eggshells for an impending disaster. It’s not worth it. If you listen to music constantly in fear of a catastrophic failure, it takes away from the ultimate enjoyment. Plus, there are just too many more advanced and not necessarily expensive DACs that’ll probably eclipse the old unit’s performance. Unless you like living in fear, don’t do it. Just my experience FWIW.
