We make some of the very few tube preamps that are **not** SET... ye olde Dynaco PAS-3 is SET, as is the Citation 1, many of the earlier ARC preamps, the CAT, the Joule Electra; Al is correct- most tube preamps are 'SET'. The term really is for *amplifiers*, where it creates a distinction, not preamps.
If you want my opinion I really feel that if you do fully differential in the preamp, there is a huge benefit there also, IOW even though there are many very musical single-ended tube preamps, they *can* be improved upon.
OK 'improved upon':
*lower noise,
*blacker backgrounds,
*far greater immunity to the length or quality of the interconnect cables,
*lower distortion/less need for negative feedback (since distortion components would be canceled with each stage of gain),
*potential for reduced number of gain stages (for example, to work with LOMC, you would need a total of three gain stages including the line section).
