It seems to make good , hard nosed economic sense, to go for High sensitivity speakers and low powered amps. High sensitivity speakers don't need to cost more, the cost maybe is reduced base output. High output, particularly with tubes, cost money, at least for reasonable quality.
I agree amp noise is an issue with plus 100db sensitivity horns, but personally, I have never liked horns. The sweetspot for me, is mid 90's, conventional box speakers. They sound great with as little as 10watts, but 20 seems a better, all round choice. My Dadalus DA-RMa speakers sound wonderful with the 20watt Ayon Spark and cheaper options like the Almarro 318B
