I'd recommend using Nichicon Fine Gold (if you can get hold of them).

Ideally for the DSP5200, replace like for like as Meridian had started to use quality capacitors for the newer DSPs.

Otherwise, look at the high-end Panasonics - but check the temperature and service life as 5200 amplifier panels run hot!
