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

Hard to imagine there is more to come from these wonderful speakers as I  reach the 100 hour mark.

Stephen, I found there was "more to come..."   :  )

Let us know what you find.

I liked the Nenuphar playing at low volume. I liked it less when the volume was cranked up.

The Nenuphar speakers, in my system and room, sound wonderful when played loud.

I attribute the ability to play them even louder than in the past to improvements I made on the power and power cable side of my system. Treating my room will push these already high volume levels, higher. My reference being: long listening sessions, at higher volumes than normal for me, without the problems that cut a session short.

I fully realize the 2A3 amps I'm using have limits in this respect. Having said that, those limits now are far higher (e.g. in volume without distortion / fatigue) than I expected and understand (technically).

I've come to learn that the types of music and how I go about listening to that music are 'tells' about my system and it's performance and parameters. One I've noticed recently is that I'm listening to large scale classical music with much greater frequency than I have in the past. This clearly communicates something (important) to me.

We all have different references and requirements. It's what makes this hobby so very interesting to me. What follows isn't dictate...it's merely an illustration of my comfort level in what my needs are:

Based my experience with Scott Sheaffer's Found-Music 2A3 amps, I (personally, for myself) do not see a need for more power than what a quality 300B SET amp offers to drive the Nenuphars.

@charles1dad   Charles, I have not brought the T+A PA 3100 HV Integrated Amp back in system since the changes to the power supply / conditioner, power cables, etc. 

I need to do so, especially since the T+A SDV 3100 HV is well on it's way to be 'broken in' (over 200 hours of playtime on it) AND the other changes are settled (for the most).

I'll make a point to do so and report back. 

David 10 I’m going to be listening to the Nenuphar 8s in a couple weeks when we get back home from sunny Florida , really look forward to that listening event , I’ve been really stumped what I want speaker wise.

We recently down sized our home and gone is my listening room above the garage along with my Magnapan speakers and Rolland amps , I now have a much smaller room where such a speaker like Cube Audio Nenuphar could possibly perform well in .
David I just noticed you’ve done some radical changes to your system I’d like to ask about your Synergistic conditioner and power cords replacing the P.I. Audio Uber and Triode wires , you can pm me if you like , thanks .
