Agreed. We are paid to do good but not ridiculous engineering. Leave that for Hollywood. Or Star Wars (the project, not the movie). 

For serious high power (3 kW to Terrawatts), three phase service is the recommended design. With a simple 6 rectifier bridge, the ripple is down to 4.2% RMS, and with a 12 pulse Delta-Wye connected dual secondary transformer, 1%. 
The need for large capacitors is eliminated, and a simple LC or just C filter is enough. This eliminates the hazardous stored energy that takes a lot of expensive parts and design care to prevent damage to amplifiers and cables.
