"Funny, I was talking about SPEC CORP the other day with the U.K. dealer friend of mine and he rated them."

Rated or hated?

@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....
