@ricardoosusa   Regarding your room size...it's also important to consider the type of room you have. Can you share more specific details beyond the size (14X18)?
@debjit_g There are so many factors in play. In other words, guidance and results may (and will) differ and vary.

Speaker positioning is a deliberate art form. You will be rewarded immensely by getting it ’right’ with respect to the Nenuphar and your room. In your case, you also have the amplifier pairing in play.

The person who helped me set them up described the "interface" as being "eutectic" with the room. [Search for Eutectic Composition and Point]. I found the ’descriptor / concept’ very helpful in moving my understanding forward.

My room is 19 by 26 with non-symmetrical aspects. For example, from my seating position, there is a large ’doorway’ in the front right corner and a very large pass through into the kitchen in line from my right shoulder all the way to the right back of the room. Perspective is from the listening position, facing my speakers.

For reference, here is a link to more information on my room:

As for the amplifier, I’m beyond pleased with the synergy and performance via my 2A3 amps and their 3.5 watts per channel. I’ve invested in pushing the 2A3 envelope even further with a custom build which is under construction. This new build is focused on maximizing sound quality (not power) so 3 watts or slightly less in terms of max power output. 
Hi @ prof,
Ironically the owners of the Nenuphars and professional reviewers point out it’s the ’lack’ of a "Lowther" shout/signature that draws them to the speakers (Amongst other sonic characteristics). It seems that actual listening experiences may be the vital factor that shapes an impression

Agree with David, no Lowther “shout”. 

Plenty of bass slam with Bakoon 13R. I have some recordings of percussion groups which clearly demonstrate this.
