Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

Every single amplifier you've listed would all be considered very good amplifiers paired with the Nenuphars.  So it seems quite clear that the Enleum 23R is pushing major buttons for your tastes. No one can accuse you of not exploring amplification options.

Hello guys!

I am a proud owner of the Nenuphar V2. I can highly recommend the integrated NAT Single HPS V2! For me that amp is one of the best tube integrated!

I'm not surprised with your outcome.  NAT audio has earned an esteemed reputation as one of the better sounding amplifier manufacturers out of eastern Europe. 50 watts class A from a gm 70 is a lot of power for the Nenuphars.  Do you utilize the optional lower power setting?

I have of course tried both modes. I personally like the normal mode with 2x 50 watts better. The Vinnie Rossi L2iSE mentioned in the above post has twice the power and should also fit very well with the Nenuphar.
A low damping factor is important! The higher the damping factor of the amplifier is the less it fits to the Nenuphar.
I have also tried the Pass INT25. This amp has a damping factor of 500. I did not like it so much! It sounded a bit harsh and less round in the midrange and also in the bass.
