Heh, I&#x27;d say tube amps are a bit more out there than everything else you listed (unless you mean tube headphone amps or something). It&#x27;s INCREDIBLY difficult to accurately emulate tubes on normal computers in real-time due to their non-linear behavior. And there is at least some kind of science behind tubes &quot;sounding better&quot; since second-order harmonics are suppose to be more enjoyable for a listener, and are generated naturally by a single-ended tube amp design. I wouldn&#x27;t say musicians using tube amps are trying to elicit memories of the past, rather that&#x27;s just the best way they can make their instrument sound good
