Indeed on the speakers. I own 95 dB speakers that are an easy 8 ohm load. The giant 84 dB speaker that takes 200 watts to wake up really don't sound any better to my ear. In general they sound worse. Give me a 90+ dB well behaved speaker every time. Then I can drive it with a 20 watt tube amp and be happy:)
As for tariffs, we shall see. Now there are more negotiations going on. One thing business hates is uncertainty. Consumers hate it too.
