Fireface 800

RME Fireface 800 is a high quality firewire audio interface. I have repaired several of these units. They all have a mix of good quality and low quality capacitors, but it's hard to predict where the bad ones are, as this varies between production runs. Your best bet is to check all capacitors with an ESR meter (in circuit) and replace those where you see variation in ESR for the same value component. On most of these boards that I've come across I've ended up replacing ALL surface mount electrolytics and the majority of the leaded electrolytics. Beware: you need a good quality soldering iron for this one. This is a lead-free board, the traces are very fragile and the holes for component legs are very tight. You are almost certain to ruin a few traces, so be prepared to do some bodge repairs.
