Reminder: how to tell current from an amp's specs?

@8th-note I’d just stop here if I was you as it will not end well.  You’re simply outgunned here.  

I have to disagree with atmasphere on the issue of low impedance Wilsons doing fine with tube amps.

Yeah, good luck with that. 
 

If I can point something else out: Just because your amplifier can drive to 2 Ohms and is able to double power as it does so does not mean its sounding its best when doing so. All amplifiers make higher distortion when driving lower impedances! If you think that distortion is inaudible think again- the increased distortion is audible as increased brightness, harshness and a reduction of detail (distortion obscures detail) because most of that added distortion is unmasked higher ordered harmonics.

Like I said before, I defer to Ralph always.

I defer to Ralph for, well, everything but thought I’d dumb it down for the rest of us.  To me, a big honkin’ transformer (sorry Ralph) and the ability to double down to 4 Ohms and maybe double again down to 2 Ohms is a good indication an amp has the balls to power most speakers (did I dumb it down enough here?).  I’m thinking Krell kinda stuff I guess.  Then again, there are obviously some tube amps that can drive certain difficult loads (like Maggies?) so the equation would seem to be, er, a bit variable.  Now I’ll let Ralph tell me where I’m wrong.
