@faustuss They are probably having financial issues.
Without any facts, that’s a huge stretch in assumption/speculation - do you have any proof? It does seem somewhat logical if retirement. Doubtful quick cash is the goal as few but likely newbies would buy a complete system. Likely better results is to sell each components at deep discount to appeal to a wider market.
The advantage of purchasing a complete system is saving time, effort, and possibly transportation costs. Some may want a great sounding system without the additional hunting - buy once and then done to enjoy. PS Audio is a solid company.
