At US$1,450, this sits above your US$1,175 median but still below the US$1,299 75th percentile only by a modest margin, so it reads as slightly ambitious rather than overpriced. Against a current-new ballpark around US$2,110 for the model family, it still leaves meaningful room versus retail, but the used ask is not a standout bargain.
What makes it worth considering is the core SPL formula: very high headroom, low distortion, and the crossfeed/monitoring flexibility that makes these amps a favorite for serious headphone and hybrid speaker setups. If the unit is clean and fully functional, the real upside is buying a well-built, studio-grade piece that has a strong reputation for transparency and control. At this price, I’d mainly want confidence on cosmetics, channel balance, and that all switching/crossfeed functions behave properly.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
