Auditioning a Tube Amp


I've never heard tubes and am seeking my first purchase. I'm going to be buying local and auditioning. What should I be looking and listening for to ensure everything is on the up and up? I'm leaning towards something newer like the Sophia Baby so as to not end up with a "project." Any specific tips appreciated.

listen to good recordings with the human voice...does it sound natural and real? see if you get an impression you are listening to music not equipment, you should get a positive emotional response that is hard for sand amps to produce
try the amp on your own speakers is the best advice

btw I have read good things about the Sophia Baby

good luck
