I have been a tube preamp owner for over 12 years. Last summer I was fortunate to home audition the KCT preamp and Krell 300 amp, completing the CAST system. Driving Eidelons, these components performed like no other solid state audio playback I had ever heard. Granted, my solid state experience is limited (Gryphon, Rowland, CJ, earlier Levinson, Threshold, Classe, Krell), predominately heard in other's set-ups, but never has such a smooth grainless presentation been my experience. Had I not fallen head-over-heels for the CAT amps, befriending my Jadis JP80MC, I would have most likely been the proud owner of the CAST system. As others have posted, your taste and priorities must be the determining factor. A local dealer may allow a home demo. Accessibility to all that's out there is nearly impossible. Recently retired, a Wisconsin dealer offered his customers trials nation-wide. I am not sure of another shop with such liberal policies, although Galen Carol has been known to send out equipment for short periods (Don't hold me to that). Good luck and if you buy the CAST system let me know what you think.
