What are the "new" brands in amps and pre-amps

Brands founded since 2013.

Forgive me. I didn't understand the term "new". I thought he
meant that, perhaps, he'd never used before. Try Doshi.

Not sure where to draw the line between new and old, so I just list the ones I have heard that do that particularly well.

Audio Research, Bel Canto, mhdt, Dynaudio, Triangle, OHM, mbl, Magico, DCS, PSB, Daedalus, Rockport, Totem, Tidal, Cathedral, Classic Audio Reproductions, Atmasphere, Nola, Magnepan, Rogue, Vandersteen, Goldenear, Krell, Classe, Martin Logan.

These are the ones I have heard that stood out. SO many other good ones.....setup and synergy is always a key.
