I agree with John that the cost of preamp tubes could be more expensive than the cost of power amp tubes. My experience has been that there are some really excellent current production power amp tubes, whereas current production small signal tubes are not nearly as good, therefore requiring NOS small signal tubes for a component to sound its best.
I still disagree that a tube preamp is the best way to start to get tube sound. IMO, it's a compromise that only gets you half way there.
