Take any budget tube amp and connect it to a pair of speakers it is comfortable driving. What you will get is a musical, perhaps an overly colorful presentation due to budget components of lesser resolving capabilities.
Take a budget solid state amp and do the same test. What you get is typically a very cold and sterile presentation lacking any tonal density or harmonic beauty.
I have heard and lived with $200 tube amps for years with great satisfaction. I could not live with any budget solid state...
Take a vintage tube amp from the earliest period, again with speakers appropriate for that vintage tube amp. Now take the earliest solid state of the late 60s/early 70's and tell me what sound like music and what doesn't
