If I'm looking for "Tube Sound", why would I put a Tube Pre in front of a SS amp?

Study " Dampening Factor " and " Woofer Control ". I've run a SS pre in front of tube mono blocks , tube pre in front of SS amp . SS to SS , integrated SS and integrated tube. My current setup is a modern tube pre to low power tube . One of my former systems was a tube pre to a Bryston 4B ST to a pair of JBL 4312a's . It didn't need subwoofers ! When the drummer hit a drum you could feel it on your chest , that's where a high( dampening factor)  power amp shines . It also comes with a large dose of ear fatigue . So I have the JBL's and a pair of Klipsh Heresy II's . Totally different sound and power requirements . But they are both 12" woofer, 3 way speakers . Apples and Oranges . I'm currently running 12 WPC tube to a pair of Zu Omens . Every combination has good points and weaknesses . My systems are all under $8k. In the medium and high priced world it's a different game and I'm not qualified .  So as far as the sound ? MUSIC IS IN THE EAR OF THE LISTENER ! The gentleman that talked about being loaned numerous tubes , is a good example of what we do for each other in the pursuit of our hobby . I am fortunate to be friends with a former shop owner that has loaned me Modwright , Rogue and Acoustic Zen products . When he spent $5k on a new pair of JL subs , I was able to participate in the setup . When he obtained $3k in acoustic treatments , I was able to audition them at his home . I'm able to borrow his pro sound meter for my setups. And when my new preamp had a hum through my headphones , he loaned me his Seinheiser headphones . I'm a lucky guy and I try to help others the same way . I hope you meet someone in your town that can help you too. Great Question , and happy listening . Respectfully , Mike .
