http://www.upscaleaudio.com/ProLogue-Three-Preamplifier_p_593.html UpscaleAudio Site inform in the second paragraph, line one, the PrimaLuna Prologue 3 preamp have two Toroidal transformers (dual mono at a low price of 1600 dollars).
But in this nice image below is clearly see some eight screws heads(see red lines) at the letf side, tipycal of laminated transformers. Then as seems there is no image on the web showing this preamp transformers, wonder if any member or PrimaLuna Prologue 3 owner may inform if the transformers are really Toroidal or Laminated type??
Thanks
