Amp question for Maggies

I drive my 20.1s with the Conrad Johnson MF2500 (better than Ice Power which I also own). Its also excellent VFM.

I have been bi-amping Magnepan 1.6QR’s with a Marchand tube electronic crossover (excellent) for some time now.  For the tweeters, I have used a VTL ST85 and a Carver 275.  I much prefer the Carver.  It is a very sweet little amp probably producing close to 90W.  For the woofers, I have used a Hafler 500, a Peachtree amp 500 and finally settled on a pair of Carver BB 350 monoblocks.  The monoblocks are incredible and I will keep them in place indefinitely though they do lack that nth degree of Solid State Slam.  I must say that the Peachtree delivers a whole lot of Bang ( and slam) for the Buck—I can’t really say anything negative about it!  

I just went from a PS Audio S300, which is similar in power to your D130, to a Bryston 4b SST2 for my 1.7is. The 500+ watts into 4 ohms, even at 90db average levels is quite noticeable. Transients are cleaner and more dynamic.

More power is better, or more like more current.

While the S300 is a fine sounding class D amp, the Bryston’s class AB with the added power is just better across the board.

If I still had maggies, on which I was using a W4S 250/500 MC amp, I would look at Underwood HiFis LSA Voyager GaN amp
That would be a great thread discussion

So many people just parrot what they've heard (which was likely parroted as well).
Having had 6 models of Maggies over the years, I can tell you a good 100 watt amp will be all you need.
