@david_ten :-))...I hear you...sorry to disappoint you, but wasn’t all that brave.

@jayctoy  they certainly are...it’s so much fun!
Hi greenhorn20, 
Nice choice of speaker color and it makes an attractive contrast to the color of the driver cone. BTW I really like the rich elegant color of the Viva Solistino. A nice room overall. Absolutes no doubt that your system sounds marvelous.

Wow, the grey looks great. Probably doesn't show fingerprints or dust as much as the black and not quite as flashy as the white, but still very sharp and modern looking.

Thanks everyone on the feedback earlier. I'm really excited about getting these speakers. Maybe I'll start another thread but I'm wondering what tube amp you'd recommend up to $5k with these speakers (used options totally ok).
@abd1 Can you share more about your needs and goals?

I learned there are far more options than I expected, due to the Nenuphars being easy speakers to drive. I was skeptical that my 2A3 amp would be sufficient, yet it was and is. I would even go so far as to recommend a 45 based SET, though with some caveats. The sweet spot from a power perspective, in my opinion, are the 300B amps.

Since you are looking at tube amps, consider those with zero negative feedback (or those that use low levels of NF).

I recommend reaching out to @charles1dad who is very knowledgeable in this area.
