@charles1dad I just started participating over at WBT.  Agreed with you on the heightened sense of community over there and the loss of it here... 

There's also so much more interest in mechanism over there.  People may fight and bicker, but they do care about why things sound differently.  And much more interest in educating others by sharing experiences and perspective.  I find it incredibly refreshing.  

Also lots of interest in high efficiency and SETs.  Right up your alley!
Hi Cal,
Not at all surprised you'd appreciate it. Yes, definitely a niche there for SET/low power amplifiers paired with high efficiency speakers. Also you have the more common high power solid state amplifiers/lower efficiency speaker crowd. But what's good is they don't spend time denigrating each other's choices.  Very good knowledge and  listening experiences shared on WBF.

This is a very good thread (Thankfully) but just not sure why the trolling and disrespectful discourse has become more prevalent on Audiogon. Seems to be worsening.

I started a thread called Cube Nenuphar’s and Mini Nenuphar’s on WBF in December 2019. Only one other posted. 
@toetapaudio,
Can’t explain that one specific example, could have been simply lack of awareness at that time. Certainly if you go through current and past threads there’s been ample discussion of similar type speakers and genre. I believe there's more exposure and awareness now.

I have a basic question powering the Nenuphars.

My listening space is very odd and not very conducive to audio. The room is a shared space, which is 14’ x 20’, with an open room configuration with high ceiling and the right side extends to another room and kitchen with total area being quiet large. However, I listen nearfield about 8.5’ from the speakers and the speakers are separated by 8’ apart.

I have been using a SIT-3 so far and find it lacks dynamics, specially is the bass region. Recently I got a chance to try a Line Magnetic 805IA (2x48W SET) and in the same room configuration, the Nenuphars came alive. All that was lacking with the SIT-3 was all fulfilled by the LM.

This makes me wonder if Nenuphars can really get along with small powered amps in not-so-small space (even with nearfield listening). I have communicated with Jon (NA Nenuphar distributor) and he thinks SIT-3 should be more than sufficient to power but my experience seems otherwise.

Any thoughts ?
