Hi Steve,

Congratulations! I believe you have made a wonderful decision in choosing the Nenuphar. Based on what I've been able to learn about this speaker from owners and reviews I feel it sets a new upper tier standard among single driver speakers. Given your current components and power amplifiers, IMHO you will have superb sound quality and beautiful music reproduction. If I were constructing a new audio system today I'd begin with the Nenuphar.

@stephendunn  It's going to be quite a Tuesday! : )

I concur with Charles.

I'm curious to learn how your Shindo source and pre sound via the Nenuphars, once the speakers are broken in.

Re. your cable question: I am using Scott Sheaffer's analog cables. If you are interested in reaching out to him, let me know. 

Synergistic Research for power and digital cables.
Thanks for your feedback, David.

Once things have settled in, I'm going to audition the Sablon speaker cables, the Synergistic Research Foundations (a relatively new cable getting some good buzz) and one other, depending on what I can get either through Cable Company or with a decent return policy.  I'll research Scott Sheaffer's cables but the Allnics I believe are out of my price range.

And thanks Charles for your encouragement.

Just FYI, these are the boxes I wanted to check during my new speaker search (started a couple of years ago) that lead me to the Nenuphars:

1.  high efficiency to work with lower powered SET "type" tube or ss amps

2. relatively small size and not too finicky about room placement

3. will sing at low volume levels

4. suitable for standard near field listening

5. accurate base down to 28HZ +/- 3db

6. holographic sound staging

7. tonally rich but accurate tone without unnatural warmth or roundness

8. priced under $12K

The Nenuphars miss slightly on items 5 and 8, but I was surprised how few speakers came that close, i. e. none.  The NSMT Model 100 (reviewed by Terry London for 6Moons) were the closest runner up, but the manufacturer recommended at least 50 watts per channel (despite being 91db efficient) and they had a separately amped bass driver which I've always been wary of seamlessly integrating.  I'm sure I missed some other possibilities out there but also sure the Nenuphars will fit the bill!

Steve,

 I believe at a lower price point the Tekton Perfect SET and the Canadian Coherent  Audio speakers may have come close to your wish list. However when many factors are taken into consideration the Nenuphar remains very formidable. I just get the sense this speaker personifies 'naturalness' which is a quality many speakers fail to achieve.

Steve, let me know about Sablon I might be able to arrange a trial.
