DeVore O/93 or PureAudioProject Duet15 for a First Watt SIT-3?

I've owned the O/93 and heard the O/96 on many occasions. I agree with fsonicsmith get the 96 if you can. I've heard the same things, one being that the woofer is substantially better designed and compromises had to be made for the 93. Hard to get a woofer to play deep and still play mids well. Both great speakers. 

I had to look them up.  Apparently "nothing brings you closer to the music".

This reference to speakers built in Brooklyn sounds suspiciously like Ohm Acoustics...and I find it somewhat startling that there could be two speaker manufacturers in Brooklyn. That said, I have never heard or heard of the ones referred to in this thread. And @ulul that looks like a pretty nice listening room and I didnt quite get what your speakers are but they look similar in design to some of the offerings from Legacy Audio. Would be interested to hear more about them and how they perform.

My speakers are named in the opening message. Are Avalon Indras, a top speakers perfect for 89db listening, less for 69db night. 

I reread your original post and I think you are proceeding on an erroneous assumption. First I hate it when people say that one speaker is better with a certain genre of music than another. This makes absolutely no sense. Other than output levels, the best rock speaker will be the best jazz speaker. I also think that your choice of amp will have more influence than the type of speaker on low level listening. Tube amps have better low level resolution and are more linear. Of course assuming a speaker that is relatively tube friendly which your Avalons are not.
