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

I would have to think the 25 Anniversary Zen would be perfect or these;

As I had mentioned, the bass may give the illusion of being "better" but I thinks it's actually just more full, resonant and natural sounding. Some people may prefer a tighter more concise representation. Upright double bass on the "Nens" with the "Zens" sounds great.

Actually Stephen, I must give you the credit for my purchase of the Nenuphars based on your review and pairing with the VR L2iSE. Since I already a VR in place, I thought your prior experience with this amp and speaker combo made the decision somewhat less risky (since I was buying without prior audition).

The challenge with Decware is finding used pieces is somewhat rare and new production is way backed up.

dspringham  Glad making the blind leap to the Nenuphars worked out.  I think many on this thread had to do the same, as did I.

The best option for matching the Decware triode SETs using the VR L2iSE as DHT pre is not exactly clear to me.  Since I prefer the balanced output,  two apparent options are A) the SE84UFO25 with the 
SBIT balanced to single end converter or B) a pair of the SE84UFO2 with XLR inputs and the Anniversary upgrades.  I have an email into Steve to
see which might be preferable.  And yes re lead time I took a gander at his build list and it is over 400 orders long!

@dspringham  Congratulations!!!

Would love to see the finish you chose. Can you link to a photo?

I'm also curious about your component chain ahead of the Vinnie Rossi?  Thanks.

you gotta love speakers like this that bring out everything that this mighty 2 watts has to offer

Highlighting the important point Dave ( @dspringham ) makes.

This despite Nenuphar specs, which suggest otherwise.

@david_ten,

"This despite Nenuphar specs, which suggest otherwise" 

Good point but only if one relies exclusively on specs and numbers on printed paper and ignore the actual words uttered by Grzegorz  Rulka. He will with patience and conviction explain precisely why the Nenuphars preform brilliantly with low power tube amplifiers (Of suitable quality)  with zero NFB and high output impedance.  Just ask him😊.

The added bonus of the Nenuphar is it is capable of performing very well with amplifiers that do not fit those clearly stated parameters. Grzegorz has been very open about the design and targeted amplification for his speaker. I readily acknowledge that there are people driving the Nenuphars with solid state amplifiers quite successfully.
