Primaluna ProLogue Five VS. Classe CA-150

I've been using my Classe CA-150 for awhile now and like it quite a bit but I've always thought tube amps were cool, do you think I'd be happier with the ProLogue 5?

I have a small pair of bookshelf speakers which aren't exactly efficient, and I do listen to electronic music quite a bit. I'd be okay with giving up a little bit of overall volume for more quality.

I would like to change things up and go for more warmth, bloom, romance if you will, but I don't want to be disappointed if I make the switch and find that I can't turn it up very loud and the bass becomes bloated or sloppy...

What do you guys think??
