If I were making and designing a SET amp, I would throw everything in my arsenal to make it the quietest possible when connected to over 100dB or higher sensitivity speakers.
Speaking for myself, using transformers with shield or better yet (potted) types and multi-stage best quality 2 or 4 pole caps is an objective and a matter of must and not a choice between one or the other.

Your amplifier design priority is incorrect. If you design for lowest noise, lowest ripple, the amp will NEVER play dynamically and it will be " dead as a door nail", compared to what others do now !!
Lowest possible ripple is NEVER a great sounding amp. It is EASILY bettered by newer designed amps with modern power supplies ( L.S.E.S. which stands for a low stored energy supply, or maybe a Flywheel ). These power supply types have " fast " power delivery, and they are able to provide precisely what is needed to the DHT Finals, on demand, to produce proper dynamics.
We are both discussing high efficiency speakers, I use 515Bs and 802Ds, horn-loaded.
