I had the Nenuphars at home for a few weeks where I listened with my SET amps: Korneff 45, Fi X 2A3 and Line Magnetic LM805ia (805 power tubes); and non-SET amps: Linear Tube Audio ZOTL40, Schiit Ragnarok, and Nord One SE NC500DM MKII Dual Mono digital amp. I used my NAT Symmetrical line preamplifier when needed. With the Nenuphars, the 2A3 had the best overall sound at lower volume, but, as I cranked things up the Nenuphars liked the Line Magnetic and Linear Tube Audio amps. My source was a Mojo Audio Deja Vu music server and Rockna Wavedream DAC. Cabling was all Clearday. The Magus speakers I heard at Jon Ver Halen's house with First Watt SIT3 and F7 amps. His source was a Pass Labs preamp with a Metrum Pavane DAC, not sure what music server he had. He was using Duelund speakers cables which had me intrigued and impressed.

So, in fact, I was comparing the speakers in the context of completely different rigs, but their superb resolution, tonality and imaging came through in both instances.
Deepfield,
Thanks for your reply.  You have a very nice collection of amplifiers.

Thanks deepfield for the information.

We are getting great results driving the Cubes with Mola Mola Makua/Kaluga’s and look forward to trying Bakoon amplification soon with the Cubes.

We have the Nenuphars at present and will be receiving Magus shortly. I’ll come back here with thoughts/findings when we have made comparisons
@deepfield  Thanks for sharing your impressions of the Nenuphar and Magus speakers. Much appreciated.
