I don't drive them hard. The room is 14'x16" and I cross over the low frequencies actively to my subwoofer so bass notes through the Maggies will be minimized.
Thanks!
Jason can likely answer that question best.
The former NuFORCE amps typically had higher damping, which is good.
That said, a quick Google shows an example of that amp on EBAY for around $1500.
For a bit more, you could move up to the NuPRIME-X Fusion 3X delivering 200W at 8Ω and 400W at 4Ω,
You would have to idle the third channel, but overall it would offer significantly better performance.
Very stable and can operate down to 3 ohms.
