Understood. In that case, I think I'll belay my Woo purchase until sometime in 2018. If I'm reading correctly, the EML step up is going to be in the $700-$1000 range on top of the amp which isn't something I'm willing to do right now. My budget is firm here, so I'd rather come back to the amp when I can get it AND the right tubes all at once than be only marginally satisfied for the next several months. So I'll probably get the Violectirc V281 or iCAN Pro for now, as I want/need a good solid state amp anyway. That's fine, really. I will be back, though. Maybe in the summer or so. Until then, thanks to all of you for the feedback. I've bookmarked all of it so that when the time comes, I'll know what to buy and for how much. Cheers, all and happy listening!
