Lush and Romantic Tube Amps

I have NYAL Futterman OTL3s. I don't know that I would characterize them as lush and romantic: they are fast, accurate, deeply transparent with a deep and actively present soundstage.

Well, Anthony Cordesman in a  Aug 7, 2018 reprint of a Sep 1, 1986 review in Stereophile said of the OTL3:

The OTL-1 is probably the best amp available for the tube fanatic seeking the maximum possible emotional impact from recorded music. ... use of the term "romantic" is the only fair way to express this design's unique character. In fact, the Futterman OTL-1 qualifies for all the best buzz words used by reviewers in characterizing the romantic tube sound: "sweet," "warm," "transparent," "dynamic," and "musical" (in the best sense of the term).

So I stand corrected.

There are probably no NYAL OTL1 amps available. OTL3s can be found, and they are the same design as the 1, just not as powerful.

​​​​​​​I think that the Atma-Sphere S-30 Mk 3.3 might be the easiest and best for you.
