It is possible to reduce ripple with poly-phase rectifiers, such as a 3-phase, 12-pulse system (which requires a special transformer with two sets of out of phase secondaries which is called a delta-wye system). Used to use them frequently for some types of cyclotron power supplies.
But generating 3-phase from single-phase, and all the rest of it, is probably going to be more trouble than its worth.

As far as I know, there isn't a simple way of obtaining a three-phase output from a single-phase input. Obtaining a multiple-phased output would require utilizing some phase-splitting active circuit. Single phase can, however, be easily obtained from a three-phase transformer, but that doesn't help where three-phase wiring isn't already provided.
Often, the most troublesome noise sources will not include post-rectifier ripple, but will include higher frequency normal-mode noise from many different potential sources, and wide-band common-mode noise, also from different potential sources. Noise is, to my thinking, one of the classic 'slippery slope' parameters in audio. With such parameters, improvement is objectively superior, but are not relevant beyond some point. Harmonic distortion is another such parameter. Continued improvement on such parameters often becomes an exercise in overkill.
I feel that it's usually more productive to spend time and energy exploring which parameters make a subjective difference to one's ears, within one's system arrangement, at one's particular location. Then, spend time, energy and money on improving those system parameters. Unfortunately, this requires an in-depth learning of of the technical issues involved. Else, one must pray, or be lucky.

Hi Ken
Totally agree with your statement. As far as whats coming out of the wall,
I guess the best that we can do is to have dedicated lines & proper earthing
just for our audio system. This is what I've done when building my house.
The rest perhaps is to add somekind of noise filter. As for the system yep
lots of tweaking , analyzing & slow deep thoughts. Diy is like a black hole,
there just never ending tweaks cause we're always looking to more out of
what we're building
Cheers
