First Bi Amping Experience

@Carlsbad2; True as to a couple of watts. However it's the transients in demanding recordings that eat the daylights out of watts. Particularly low frequencies. It take a LOT of current to move woofers at high SPLs with difficult tracks. That's where the reserve or "margin" that big subwoofer wattage comes in handy. 

In my system I added a pair of Bryston 700Bs to drive my 6 woofers (tube amp for the mid/tweets) and the difference in bass and musicality was substantial. 

Well said @ellajeanelle. As a 62 year old man I still love the punch and slam of powerful bass. Cello, tympanies, string bass, lower octaves on the piano all demand a lot from my rig. Ditto for Rammstein's Du Hast Nich. Without slam it's just not as fun- and music should be fun.  In fact I think I'll take Mahler's Appalachian Spring  off my que and crank out some Benny Basssini loud enough for certain grumpy old farts to get offended. After that perhaps some Scorpions followed by a shot of Ted Nugent- like you said: Because I can. :)
