Don't forget the Lundahl xformer based step-up from
Kevin Carter of K&K Audio.
This is *also* available in kit form for just $225! Kevin is a really nice fellow & will assemble the kit for you for under $300 total (i.e. kit + labour).
The Lundahl xformers are amorphous core & their sound characteristic is much more natural than any other xformer core metal (such as permalloy or mu-metal).
This is a serious contender against the TX102.
My friend (who owns a SP-6A) has a pair of these installed inside the preamp chassis. Results are simply excellent.
IMHO.
