I had Martin logan sequel2 which is the same sl3 but older model (I am not sure).I listened to these speakers with all kinds of amps and I just have to say problem is not the amps.The only amp that could challenge with this monster was my Bryston 7bsst wich is I still have it in my system.They need a lot of power to sing and your amp will run very hot.If you never had electrostatic speakers befor.I would say forget the Martin logan and go with dynamic speakers or if you are a big fun of these kinds of speakers I would prefer Quad over Martin logans.This speakers are not good with all kinds of musics and they do not rock.Some people saying that they good for jazz and classical but in my opinion,If your speakers are not fine with everything they are toys not speakers.Forget about looks,color,size,name and advertisments in stereophile because major of this products has been made to make some money.Go look for a pair speakers that makes you smile when you sit front it.
