Tradeoffs going to a hybrid from all tubes?

Hybrids seem to make a lot of sense, especially with a limited budget. For much of what I listen to my Totem Forests sound fantastic with the JoLida I have ...just that occasionally, I'd like things louder without cranking the volume knob to 3 o'clock. Am thinking a hybrid might be the way to go. Budget would be in the $1000-$1500 price range; used is OK. JoLida 1501A looking very affordable at <$700 shipped. Thanks in advance for your input and any product suggestions (I did find an earlier thread on recommended hybrids).
