Default One bridge ok for stereo UCD400 amp?

Hello all, this is my first post. I am helping a friend build some compact amplifiers for his digital jukeboxes. We will be using 2 UCD400 modules running from a 625VA 40+40 toroidal. Our aim is to keep it as simple as possible. Is it ok to run 2 modules from a single rectifier and 4*10,000uf caps? Sound quality is not ultra-critical in this aplication, as they will be in commercial environments, but minimum component count is vital due to the small enclosure. Also, they will be fed from a computer sound card, are there any earthing issues I need to address? I am a little concerned about earth loops in this setup.

Thanks for any advice
