Why do Tube Amps sound more romantic v SS amps

I didn't have any interest in tube based amps, until I purchased an efficient pair of speakers. After researching various amps, I went with an 845 18W SET 'A' IA, and have throughly enjoyed listening to the music it conveys. I also replaced my SS DAC, with a tube based DAC. My knowledge of tube families and how they sound is shallow, I have swapped tubes in my DAC. 

Tube or SS?  Who cares listen to the music not the gear.

Says you.

I like to listen to the gear sometimes. I like to focus on the sound not the music. 

If music was the only point, as you suggest, no one would be filling this forum about how things sound. But they do. 

"Audiophile" is a lover of sound. 

In the field of electronics and sound production, HiFi has a requirement to produce and electronics that is purifying the sound being produced.

All other electronics produced for sound production are usually designed to distort sound in some shape or form, or control sound that is to be recorded.

In the world of listening to music where electronics are involved, it is nearly all listening to the Gear and the Sound that is a result of the Gear.

Meet an Acoustic Guitarist Performing in an Open Place with only the guitar, is as natural a sound as one can hope for, meet the same Acoustic Guitar and a Microphone and Amp is involved, not so Natural a Sound, meet the same Acoustic Guitar Plugged into an Amp and sound produced via a speaker, not natural.

Meet an Electric Guitar plugged into a selection of foot peddle sound control boxes and Amp, listened to through Speakers, definitely listening to the Sound produced by the Gear, as a result of the Guitarists capabilities.

Put any of the above into a recording studio, and through a mixing consul.

Well the gist is outlined.        

Sadly, the warmpth of the tube amp is caused by the 2nd order harmonic distortion the tube amps tend to produce. You will notice that often, tube amp's power rating re rated at 1% to 10% harmonic distortion. It gives a richer, more "warm" sound that people like. Buy the gear that makes you happy!  All of us hear differently; our ears are shaped differently. Beautifully made guitars have a richer sound because the string's harmonics are excited by the player's activity and make it through to the soundboard of the instrument and into the air. They sound "fuller" and "richer" because of it.  Enjoy the music and forget about a bunch of numbers.

@pindac did not say a thing other than Tube DAC and Tube Phone Pre. 

SS is fine just fine. 

@hilde45 you do you. I do me and have both topologies in my system.

Its about music and music is sound. Or for some they may listen to white noise.
