@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].
