@david_ten Thanks. Considering the amps that have been stepping stones leading up to the Enleum AMP 23R--LTA ZOTL Ultralinear, FW SIT 3, FW SIT 1, Tektron 2A3, Pass Labs 25 INT, Vinnie Rossi L2iSE, Decware 25th Anniversary Zen Triode--yes, I think this is "IT".  It's been an interesting and enlightening journey.

But I’m always interested in what you or others have found to be your "this is IT amp" with the Nenuphars.

@stephendunn 

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! 

@v10 

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?
