Interesting, though I don't agree with your observation. I observe that the Rogue Amps seem to sell well compared to other equipment, and depreciate less than most equipment. This varies to a certain degree with models; the magnums sell quicker. I have considered a Rogue pre-amp for a long time, (I am auditioning one now) therefore watching their comings and goings and have found they move well before most sellers are inclined to negotiate on price.
What sells fastest is any piece well below average price.
