I have been wanting to try using a tube amp.

I have been wanting to try using a tube amp. I am using a McIntosh 6700 solid state. It seems with work and family things that the best I can get most days is maybe 1 hour of music listening with no distractions. If I have to wait 30 minutes for a tube amp to come to temp for best sound, I think I will feel shortchanged. Should I go for it anyway. I have been looking at Raven Audio. I like their cables, but would be rolling the dice, as their is no way to hear the amp in person. Any constructive advice.
