Woo Audio 6SE Tube headphone amplifier with Sophia tube

I have a trade-in Woo Audio 6SE headphone amp in excellent condition for sale. It comes with an extra Sophia tube that is supposed to be the hot ticket for the amp.

The WA6SE is a Single-ended Triode Class-A, All Tube Drive, Output Transformer Coupled
design.

Reviews have all been excellent:

Part Time Audiophile said:
Overall the Woo WA6SE packs plenty of punch tied to a tonal richness
that can stand toe to toe with any headphone amplifier in its price
range. It is the classic amp of its time, built with a keen eye for
detail and a welcome sense of longevity that makes you think it’s one
of those pieces that you could hand down to your kids. The build is in a
class all its own, one that far exceeds its price bracket. The
fine craftsmanship of its construct is just a window into the
capabilities of its inner sonic beauty. If tubes are your thing, then
Jack Wu is your man. While many of Jack’s products would be a great
addition to any audiophiles collection the WA6-SE will strike a sweet
spot in the price to performance balance for many. It’s power output is
as impressive as it’s aesthetics.

Other review quotes:
