Match Amp w/Tekton Design Lore

How about a few more details... what source are you using?  Room size.  Distance apart.  Distance out from walls. 

I have the lores...10’ apart. 30” out from the walls. Driven by an oppo 205 into a belles 22a tube hybrid pre into a halo a23 poweramp with a powersound audio s1500 sub to fill in the bottom.  At 12’ back at the listening position @85 dB the soundstage is massive and deep... and the sound is refined, powerful and musical... and I doubt I’m using more than 3-4 watts of actual amplifier power. 

If you look up the specs on the audax gold tweeter, its rated at 94.5 db at 2.8 volts.  The legend B102 is rated at 92.4 db....so, maybe a single Lore is closer to 94 db than 98db.  Even so, if your look at the Madisound spec sheet, the tweeter tested at about 101db output at 5 volts (2-3 watts?)  So, how loud do you want the Lores to play??

Five years ago, if you look at the forums, people were having tweeter failures when they played the lores very loud, seemingly for home theater using home theater recievers....and then Tekton noted that their warranty did not cover burnt voice coils.

I have them in a 10,000 cubic foot room, and as I said, they sould great at 85db (peaks hitting 90db)...and I can easily turn them up louder to the point of being uncomfortable and unsafe for my hearing.

So, is the spec bogus....assuming one Lore measures 94 db, then two together would be 97db...which is within a measurement tolerance...so my view has been that this is a great sounding loudspeaker, fairly priced, super easy to drive with specs that are pretty close to correct.

Dynamic is absolutely a word I would use to describe the Lores.  When you look through many of the threads and comments about high efficiency loudspeakers like the Tektons, Zu, Spatial Audio, etc.....you get a perspective of the different sound/presentation people get with Triodes, non triode tube versions, solid state amps, etc....usually, but not always, lots more "punch" and dynamics with solid state...but a somewhat less holographic sound...which can be partially offset with a tube preamp.

It sounds to me like you are at the point where trying a few different amps would be of value....and I'm pretty sure that being 5' out from the rear wall, you are losing low end....and by not using the sub you are losing some ambiance.

I like this post from Steve Guttenberg to describe dynamic. It’s not an exact definition but pretty good.

I don't think there is any question that audio is like programming in that GIGO....so, given that... five years ago I was using a 10 year old $500 Sony CD player...I replaced it with a $500 Oppo 103...the differences in almost ever respect were shockingly better.  This year ( 5 years later) I replaced the Oppo 103 with an Oppo 205 expecting a modest improvement....wrong...the improvement was again shockingly better in terms of clarity, detail, space management, 3d sound stage, deep bass....and on and on...so, in addition to moving the speakers and the furniture, you might seriously consider a DAC upgrade...something from Audio Advisors that is returnable if it doesn't do the trick.

One more thing...the room is a key part of the overall sound and every loudspeaker couples with the room differently (hence your bookshelves sound different than the Lores).  Opinions are all over the map but I've always found that a room that is a little more live than dead delivers a sound that is more real than clinical....so, just for fun, you may try moving some of the furniture and doing other things to change the sound characteristics of the room....then at least you will know, even if you can't leave it that way.
