Hi, I have a Yamaha RX-570 Receiver that's in great shape but want to start replacing caps as it is 20 years old now. The power supply caps in now are 6800uf 56v. Now do I have to stay at that or can I go to 8200uf 63v? I'm looking to replace them with Mundorf M-Lytic AG Series. I can get them in both sizes but only in 63v they don't have 56v does that matter?
Specs:
Two-channel receiver with 70 watts rms X2.
THD, IM<0.019% at full power, 20Hz-20kHz.
Very quiet line and phono preamp stages.
Dual mono construction of power amp section.
Tuner has very good sensitivity (-50 db quieting: 15.1/37.7 dBf mono/stereo), selectivity (85dB), and quieting (81 dB mono/76 dB stereo S/N).
Full power bandwidth rated as 10Hz to 50 kHz. Dimensions:430 x 140 x 340mm (Width x Height x Depth) Weight:9kg (19.8lbs) Year:~1994.
Thanks.

A higher voltage rating is always better, up to perhaps twice as much voltage as you need. It's very likely that the rectifiers
can take more bulk capacitance, even up to 10,000uF.
Yes, it will be fine. I would go with 10 000 instead, as it is a much more common (and thus cheaper) value.
But you're wasting your money buying Mundorf parts. Get something from a reputable manufacturer instead (Panasonic, Samwha, Nichicon, etc). You'll pay way less, and the quality will be higher (or equal, in a worst-case scenario). I honestly don't think Mundorf could ever match a real professional capacitor manufacturer, with real research and know-how.

You sure can go with higher values as others have already said. The thing to watch out for in that case is the physical dimensions. Make sure that the new ones will physically fit in the place of the old ones. Obviously height and diameter are the main physical dimensions, but also ensure that the pin spacing is the same especially is they are PCB mounted capacitors.
I'm also a proponent of using capacitors from a well known, quality manufacturer. Panasonic, Cornell Dubilier, Elna or Rubycon to name a few.
