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

Rated or hated? 😂  He liked them.

@rwpollock   Robert, thanks for sharing your experience with the SPEC integrated amp and congratulations on finding another successful and satisfying pairing for your Nenuphars.

Paired with my Nenuphars, the SPEC was in the upper echelon, keeping company with my SIT-2 and Vinnie Rossi integrated.

Mr. Shirokazu Yazaki's (and his design team's) efforts have been on my radar, for some time now, because of what you eloquently concluded:

"The amp isn't about that bump in the upper mid-bass; the focus is on tone. Instead of listening with my forebrain I find myself listening a little deeper."

I encourage those curious about SPEC to read Jeff Day's Positive Feedback review, which Robert linked in his post. It is thorough and complete...wish more reviews were as well done.

Some might find the SPEC to not be incisive enough. If so, that can be cured by pairing it with your favorite preamp....

An update that's a non-update. : )

The comparison of the Found Music 2A3 amps directly into the Furutech wall outlets to the 2A3 amps direct into the SR PowerCell is taking longer than I expected. 

Both 'powering chains' are resulting in beautiful music. Many more similarities than differences. No clear preference. At this time.

I've chosen not to complicate things by introducing the T+A amp into the mix. I'll wait until I've reached a conclusion and/or choice regarding the 2A3 amps directly into the wall OR into the SR PowerCell.

I consider/find the 2A3 amps to be fully run in now. They have over 1200 hours of active play time on them. They have been stable in my system, post hurricane Ida electricity restoration and the Furutech install, for over 350 hours.

I also believe the Furutech outlets are run in to my satisfaction. They have over 200 hours of active play time. And over 340 hours drawing current. [Note: this is contrary to what many report].

New owner here... Nenuphar in Smoked Eucalyptus (piano gloss finish). Coming from Harbeth 40.1 and Raidho D1.1. Very impressed with this speaker. All the accolades as already mentioned in this thread.

Began use with Vinnie Rossi L2iSE (Elrog 300B and Linlai Global E-2A3). Very nice sound per other users here - HOWEVER - took a chance an a preowned purchase of a Decware Super Zen SE84UFO2 (V-Caps). Wasn’t sure if 2-watts would do it but holy cow! Using the Rossi as DHT preamp feeding the Decware proved to be quite a surprise. With Decware silver interconnects and speaker cable the sound is strong (at my conservative listening levels) with impressive detail, depth, separation and wonderful tonality.

I think this configuration drips with tube goodness. Not lush, solid state fast, really good frequency extension at both ends of the spectrum. Believe the bass sounds stronger with the Decware than with the 100 w/channel Rossi output ss output section (once again, at moderate SPL’s). Maybe something to do with damping - bass just sounds more full and resonant (maybe less tight and controlled but more realistic with my acoustic and jazz music preferences). Highs are airy and crisp. Steel guitar strings have that "bronzy" sheen. Vocals (ie Mark Knopfler) are gripping and gravely as they should be

So, seems like nice match with the Cube’s. This little Decware is impressive but you gotta love speakers like this that bring out everything that this mighty 2 watts has to offer with it’s short, bare-bones signal path.

Regarding DHT tubes, I prefer the Linlai 2A3’s with the Rossi’s internal FET amp and the Elrogs with the Rossi in preamp only duty with the Decware.

Cheers...
