I wouldn't. I don't know why this is stated over and over again with no data to back it. Absent that, I think they are either following the crowd, or visual impression of a tube product makes them think it sounds better than it does.
Some adopt tube amps because they go to a friend's house, hear his complete system including tubes and goes home thinking he also needs tube amps, forgetting about everything else that was different. The height of silliness is them coming back thinking they should buy all the same cables! That, we know is not based on facts.
Sure, a guy who over 30 years has owned a dozen speakers and two dozens of amplifiers and several record and CD players and has consistently preferred the less accurate equipment did so because cables and his friend's tubes.
