Is a Bryston 3B SST2 enough for Magnepan 3.7i or 20.7?

Hello,

I currently have a Bryston 3B SST2 with BP26 Preamp.  My current speakers are Magnepan .7s with a small KEF sub.  I love the combination but am getting the upgrade bug.  

I'm just not sure the 3B SST2 has enough power to drive the 3.7i's or even the 20.7s well.  I do not listen at very high volume levels, as a good deal of my listening is late at night after everyone else is asleep.  That is another concern is that will the amp drive them well at very low volume?  Not sure I would need the sub with the 3.7s or 20.7s.

Appreciate any thoughts from Bryston and Maggie owners.

Thanks,

GK

Sorry man , You can throw all the mathematical equations out to support a low power amp will drive a speaker the same as a larger amp does  . If the speaker was 100 db efficient , then we can say that will work . Not going to happen with magnepan though .

Yeah , Stick with the 3 series and be content . Bryston makes larger amps for the hell of it .

Please explain how a 200W amp has more bass than a 100W amp when only using 50W.

Speaker efficiency is irrelevant. You stated more powerful amps have more bass than less power amps even at low listening levels. I stated that it’s impossible simply because that’s not how it works.

Just get any 50 watt amp . Its all you will ever need for one of the hardest to drive speakers on the market. Great advice . Any more brilliant pointers we should be aware of ?
