just a FYI......i had two Don Garber Fi integrated 2a3 amps, one with Hashimoto and the other with Magnequest.....the difference in sound was substantial, Magnequest was much better, and more focused.
That was the second amp i had with Hashimoto, the other a Triode Labs integrated and again in that circuit they sounded lean and flat (maybe I mean more linear less passion) that the Fi.
