Why do Tube Amps sound more romantic v SS amps

My approach is to use a hybrid. To my ears, Tubes are really good for Mids and Highs, and SS is good for Low. I drive my Midrange and tweeter with tubes (Class A SE 300b 20w x2), and the bass is handled by Subwoofers (Class D x2). For me, this gives me the best sound which works for diverse genera. It all bottles down to preference. 

Hard to generalize - horses for courses.

I just try a given amp out in a system and then compare with whatever else I have at the time and choose whichever set up sound s the best to me.

I run all tube into some big Wilsons, but solid state into a pair of electrostatics and also into some big Vandersteens.

I am less interested in trying to find a 'rule' about what sounds better and more concerned with using what does sound best in a given system.

Talk about beating a dead horse. How many discussions have there been between solid state vs. tubes. Belt vs. direct drive. Moving coil vs. moving iron.

There are no hard fast rules. It all depends on the design and build quality. And personal preference.

Tubes in my mind are more for equipment hobbyists who like to experiment without changing boxes. And don't mind the heat/increased AC bill.

I had SS for decades. Then a buddy brought over a tube amp for me to try in the rig. The difference was like night and day. Even my wife, who really doesn’t care that much, commented on how much better the tube amp sounded.

The last couple of years I’ve had four different tube amps in my rig. Two that friends have let me try and two that I’ve purchased. They are in order: Prima Luna Dialogue One integrated, Dynaco ST-70 power, Prima Luna EVO400 power, NAT Audio 805 Generator mono blocks.

Partner doesn’t care about my system… it is my thing… but she instantly liked tubes when I put them in my system (women typically have much better hearing than males and are very sensitive to high frequency distortion). 
 

Once I moved to tubes in a component, there has been no going back.

The advantage of tubes.

1. When you have a sound change because of worn drivers or outputs you pop in a new tube and presto, like a new amp. 

2. You can change the sound for your new speakers by changing tubes. For me trading out the EL34s for KT77s was a large improvement in sound. 

3. The tube preamp tubes can also change the sound as well to taylor and component matching.

Tube vs transistor sound is personal taste as far as what you like in sound and the differences between them. Both are great depending on how it is matched with the components you have. Enjoy both!

SS amps have come a long way in the new $1K and higher cost designs. However, the right tubes can play with an immediate sound that isextremely open and just great. I never heard a SS amp quite as good in this respect. But, most tube sound is accomplished in the tube preamp section and I would be ok with a tube preamp and SS power amp.

You don't have to understand how a tube works to know if you like-em. No solid state device can sound like a tube for audio. But if you can combine tubes with solid state, you get the best of both worlds, nothing new about this design. One of my amps uses a triode tube on the input and power mosfets in the output stage. It sounds magnificent to say the least, with a full midrange. When I remove my ss amp and install the hybrid, its like day and night, and the enjoyment level goes way up.
