Why do Tube Amps sound more romantic v SS amps

Now good tube gear can have it all (almost) , wide flat frequency response that was not possible in the past.   I've had all , SS.  a mix of Tube and SS, and all tube.   Itend to prefer what tubes can do in my system with my speakers.  

Like others have said, its the way they distort and the fact they sof clip when you push them.  Poor matching of speaker to a  tube amp will not be so romantic....

They sound different because they are electrically different.This provides an excellent explanation of those differences.

Yes , and you will never be able to duplicate the sound of something like a 2a3 or 300b with silicon.   

Class A SS can be just as ‘romantic’ as 2A3 or 300B driven electronics. Not all electronics (pre or amp) with tubes are romantic sounding. The key is implementation and designers pedigree in both topologies.

That is true.   Yeas ago I tried a Pass Aleph 3 and it sounded awesome.   My speakers were a poor match     Plus it ran hot as hell so at the time it wasn’t for me.  
 

It was purple colored it got so hot.
