Not exclusively tubes. One of the most impressive sounding set-up was NAD monoblocks and K-horns. But that was sometime in mid 80's, and nowdays choices are virtualy unlimited. You might be able to get nice SET amps, or even push-pull amplifier, but matching it with high quality pre-amp will be matter of chance. My suggestion would be Perreaux solid state Pre/amp that you can find discounted on the Audio Advisor web-site.

You just have to hear Carmina Borana with K-horns and high current amp! Good luck!
