Hi Jfrech, You should try to audition both in your own system so you can reach your own conclusion. I can tell you that I'm hearing wonderful things about the new SE amps from BAT including the SE upgrade for the 60 although I haven't heard them myself as of yet. I have heard the same system with a stereo 60 and mono 60's and can tell you it's not just a matter of playing louder. Yes the mono's will play a little louder but there is many other sonic benifits. For one the soundstage will increase in size with more air and the images will solidify with greater focus. Bass will be much improved as the mono amp will have greater control over the woofer adding extension and slam to the bottom octaves. Transients will be much quicker with a greater jump factor as the sound will have greater conviction, authority, and ease. Timbre and texture of tone be it instrument or voice will have more refinement and sound more "there". You could make a parallel to athletes where they both do the the same task but the one that is better just makes it look so much easier and natural. The beauty of the BAT design beside that they sound great is that the future is there for improvement as your audio budget increases. The upgrade path from stereo to mono and their SE counterparts be it a 60 or 75 lay ahead if you wish. One guy I heard of had VK 1000's for the bass and 4 VK60's for the mid and highs on a pair of Dunlavys. Wish you all the best. Tom
