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

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.

@v10 Welcome! I’ve been very curious about a GM70 pairing with the Nenuphars. Great to hear you are loving your NAT - V2 combo. The Single HPS looks like quite the build. Thanks for posting your results with the NAT and how it easily bettered the Pass XA25.
