Are 450VDC Solen Caps the wrong choice?

Im upgrading the caps in an old pair of Marantz Speakers. Each speaker uses (2) 10uf 50VDC and (1) 33uf 60VDC Culver caps. I bought Solen caps to replace them with ( same values, ie 10uf and 33uf), but noticed they are rated for 450VDC. Is this a good thing or bad. Cost is not an issue and even though the Solens are physically much larger its not an issue.Would I be better off with caps rated at 250 VDC? I want to go with the Solen. It seems all quality metallized polypropylene are either 250 or 450 VDC. Speakers are rated at 250 watts RMS max , amp puts out 125 wpc . THANKS for any help.
