I’m breaking in the HP phono stage in my Rowland Continuum s2 integrated amp right now. I never heard the Pass phono stage but did have a couple of Pass amps in my system in the last few years. As far as amps go, I prefer the Rowland sound over Pass. Pass sounds veiled while Rowland has a cleaner sound with better tonality to my ears. I find Pass to be boring. I once considered the Pass phono stage until I heard their amps.
