I would like impressions of Tekton Lore and Lore S

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 have the lore s. They are as described and I really like them. But I think the bass has less impact than the regular lore. If that's important to you, may not like the lore s.

I have had the Lore for about two and a half years now. After about a year I swapped with a guy who had bought the Lore S for about a week because his wife didn't like the finish on his Lore S, and we both wanted to try the other type of Lore. We agreed if either of us wanted to trade back, we would honor it and swap back no matter what.

In that couple weeks trial, it was clear from the first moment that the Lore S has more detail, dimensionality, and hi fit character than the base Lore. However, the Lore has a more energetic sound, and a soundstage that fills the room much better. It has a more "live" sound. For all the improvements with the Lore S, I couldn't live without those essential qualities of the Lore. Others may feel differently, but that's what I determined for my system and tastes.

It sounds like you might have similar tastes. You might certainly consider trying the Lore. In addition, several months ago I went ahead and rebuilt the crossovers with high quality capacitors and resistors and upgraded the internal wire to solid core silver. That made a big difference in the imaging and other audiophile characteristics while retaining the raw energy of the eminence driver. It certainly didn't close the gap on those items between Lore and Lore S, but it was a big improvement for sure. You might consider upgraded crossover components If you need the eminence presence and energy, but want a bit more of the audiophile character as well. And I didn't even go with the high cost mundorf silver level of capacitors, either, but a step or two below that in cost.

What is the low level dynamics and tone like for lower level listening compared to when the volume is up?

bcgator, I called Eric using the number on the website and he answered. We talked about the Pendragons which i'm considering to purchase. I'm reluctant to buy a speaker I haven't auditioned and the return policy says there's a 20% restocking fee not to mention shipping such a large speaker then if damaged in shipping a discount in the refund. That could be a costly price to pay should I not like them but Eric was a nice man to talk to. To say he is enthusiastic about building a great speaker is an understatement.
Cheers
