The extremes tend to enforce diminishing returns. Good-sounding tube amps that are quiet enough, and sound good, are probably rare and expensive... depending on how one defines "quiet enough" and "sound good".I think SETs tend to sound best with high efficiency. To work well in ultra-high efficiency settings, ideally, filament supplies are well-sorted, grounding well-arranged, and power supplies have low-ripple and good damping. For good sound, I like power supplies to have low enough impedance and fast enough recovery (though relieving the amp of large bass transients may reduce the recovery requirement). Most designs don't achieve all that. Moreover, ultra-high efficiency is revealing, so exemplary design and implementation are essential too. Expensive.
Or, one can chuck a mediocre SET amp on those speakers and find it wonderful and the noise not distracting. Go figure.
