There is an older post here that you may want to see. Paradigm makes excellent speakers but the Stratus line of PSB is hard to beat. I was in same situation and chose the PSB. I was not able to hear them side by side as since they are in a similar niche, few dealers carry both lines. I found that in general the PSB were more of a relaxed and slightly relaxed but that the Paradigms have a slight edge in the bass response. I think it was Sensible Sound that has reviewed the Stratus Gold and the Paradigm 100's and they said that yes the Stratus speakears were more accurate but not by a wide margin and they are more expensive than the Paradigm. I however felt the Stratus was worth the money.
Paradigm vs. PSB
I'm presently comparing PSB Silvers or 800i series to Paradigms monitor 7 or reference 1 for a purchase in the next week. Unfortunately no dealer carries both to compare side by side. i would appreciate any wisdom and guidance you could provide. They are similar in size and appearance and specs. I have an Onkyo M504 amp/preamp. Thank you!
