I used to own the 339,and while it was good,it wasnt in the same league as a Glenn or a WA2,or some of the other amps being mentioned here.
If the OP had a budget under a grand,I'd give a hard look at the 339,but he can get better with his budget.
After contacting the builder of the Citadel/Oblivion amp it seems like it costs a fortune to ship any of his amps(they are freaking huge).
So I went looking for the WA2 you mentioned here and they ship for free!, and I am asking if it's comparable and good alternative to the GOTL for a $1200 shipped? (shipping amps like this one to my country usually cost ~$130).
