Thanks for an excellent review. Can you provide a little insight between the HD800 running in balanced out of GSX vesurs single-ended out of the Woo 5? I know that the GS-X MKII with the HD800 is outstanding but how about compared to the Woo. Several years back (maybe five years), I auditioned the WA5 with Sophia princess tube and thought highly of it.
The differences while subtle were noticeable. The WA5 has the wider soundstage and more transparency. The tonality is spot on instruments and musicality is indeed very special. The hD800 on the MK2 is excellent as well very dynamic but loses some of the soundstage width and depth that the WA5 and most well designed tube amps provide. Section of tubes is also important for the WA5.
