I highly dissagree with people trying to justify the price of this hardware due to the fact that it can drive speakers (btw I used to own a tricked out WA5). You can find a killer...and I mean...killer, speaker amp on audiogon for a lot less than that, and I can almost guarantee you that it will sound better than something designed to be a headphone amp and speaker amp in one. You can almost guarantee that it won't be a push pull amp since it isn't powerful enough (maybe push pull 2A3 tubes?)...meaning it will most likely be a regular SET amp of sorts in my opinion. Also, that much money for a 8 watt speaker tube amp is a little crazy in my opinion.
Buy a BHSE for half the price and be done with it
They have terrific resale value which I can guarantee you a tricked out Woo amp won't.
