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

I’ve seen this amp and was also intrigued by the switchable damping factor. How did it sound with the DF set at 250?

Anyone try any of the Luxman Class A integrateds with Nenuphars? I am curious to try the L590axII integrated and just simplify to that and a dac/streamer.

How did it sound with the higher damping factor. Better than expected -- a little drier perhaps and a shallower soundstage.

By the way, word is that Nelson has found a new source of industrial SITs. Apparently they are larger and produce more heat. There is a SIT-4 in the works, but it may be a monoblock configuration to dissipate the heat.

@toetapaudio are you UK based and running the 23R?  Please drop me a PM if you are.

@realworldaudio - great videos, I came across your channel a while back and have learnt a lot - so thanks!  Have you ever heard the Cube in TQWT or MLTL vs your Voigt pipe?  Difficult to know which enclosure best suits the Cube drivers...

Why F8 Magnus over F10 select?  Seems as though the F8 Magnus has somewhat smoother frequency response...

@gavin1977 I had Bakoon 13R, very similar. Worked well imo with Nenuphar’s. 

Just had a demo of a pair of Cube Audio Jazzon and Nenuphar - pretty similar level of performance to be honest, with the Nenuphar having an smidge more polish, detail and soundstage - but I would happily go for the F10 select given the cost/benefit ratio.

The F10 Select driver holds a lot of promise, detailed, dynamic, it does bass and has great width/height to the soundstage. But it was (for me) shouty and lacked soundstage depth because it was so forward in the vocal region. This was the same with two different amplifiers a 300b and an Enleum/Bakoon.

If the FR was equalised, and the presence region pushed back into the mix, then would this add depth to the soundstage as well as taming it shouty nature?

It’s a very tempting solution, but I still wonder if EQ is enough to ‘do the trick’ of righting the wrongs of a full range driver or if I should just stick with point source, but using multiple drivers…
 

…Or perhaps I should have listened to the F8 Magnus - smoother and more consistent frequency response by the looks of it?

Anyone else have a similar experience?
