Tube pre-amp with SS Classe Amp


Please help me chosing a tube pre-amp to match with SS CA-201 driving BW 804 Nautilus speaker. Currently using SS Pre-amp CDP-50.
thanks

The Sonic Frontiers products due to the fact that they are DC coupled, low output impedence (for a tube product) and fully balanced are excellent companions to many solid state amplifiers sharing these design parameters (w/ corresponding low input impedences). The higher you go up in the line the more compatible these tube pre amps are to solid state amps. They are well built with nice convience features. How ever they tend to be more neutral and less euphonic than many other tube preamps in IMHO.
Check out the Cary SLP 2002. It's got everything you want and more. Make sure you get a discount. 20% seems about right.
Have anyone compare the BAT VK30, Cary SPL-2002, and SF L2 side by side with Classe amp?
