I think you answered your own question,,, The Lore's will give you MORE of what the M Lore's give (dynamics and live sounding) and in Eric's own words the Lore S is a more "refined or HiFi-ish" sounding speaker.
I would like impressions of Tekton Lore and Lore S
I have used the Tekton M-Lore and was very impressed. Considered getting a pair of Lore's for larger transducer and upgraded tweeter. I really like the character of the Eminence driver. I ran across a pair of Lore S's which Eric said I would find more refined. They are considering the European components and the top end is sweet but I can't get past not having that slap or slam that came out of the Eminence. Maybe I overshot my target and should step back to the Lore's? Anyone out there who has any thoughts on this matter your feedback would be appreciated. Sure miss those local Hi-Fi shops. I have been a musician and audiophile ie. nut since the 70's and have had it all. Tektons are the only speaker I will ever listen to for reasons to countless to mention. Let me say that E.A. has a special gift for what he does.
