The DK Design VS-1 Mk2 with a tube preamp stage and a solid state output stage is liquid and crystal clear with a rather pellucid presentation. It is also a beautiful design and built like a tank. I would be very surprised if anything at any price sounds appreciably better through a high resolution system.
An all tube integrated design will not likely have a lot of bass impact unless you have very efficient speakers and Jazz and Classical contain a lot of bass information. Maybe with horns..
As far as all solid state goes, I would seriously consider the Plinius integrated even if it is relatively inexpensive. Their separate amps are easily some of the best sounding available at any price and the integrateds retain much of the same character of sound. Unless you are using ribbons or electrostatics(and even then)you'll approach the liquidity of tubes and retain the phenomenal bass response this equipment is known for.
