Check out the Cronus from Rogue Audio for your price range ($1795 new). Good punch and very versatile bang for the buck (it even has a phono stage). It isn't always civil with quiet or acoustic material, but if you are looking for punch, you probably don't care.
If you can spend a few bucks more (about $2500 new I think), my favorite bang for the buck intro level tube integrated is the Manley Stingray. I even liked it over the much more expensive ($3795) Audio Research VSi55. I've had one for just over a year and so long as you feed it a signal from a quality source it will deliver all the punch and dynamics you would expect from separates at twice the price.
Good luck!
