Yes, it is a current 6N1P equipped Transcendence Eight preamp, and the sale offer appears to be very authentic.
If we had the unit here selling it used, we would ask about 75% of new price ($1300 to $1400) with a new three year factory parts and labor warranty on an essentially new product.
The asking price of $1000 for this unit is unusually low. The owner must really want to get rid of it. We often know the audiophiles want to get out of their old equipment in the worst way, and often do.

Want a T8? Nab this unit off right now! The T8 is a very special unit, the buyer will wonder why the seller parted with it.
Note that the remainder of the three year factory warranty passes on to the used buyer (one time).
