Tekton Double Impacts

Thank you grannyring.
I think you are spot on as far as the sound goes. The setup with the DIs is not warm or wet tubey sounding .even with the Rogue St-100
It sounds real .It is not a "romantic" sounding setup. I have had cables and gear that lends to that , but the other thing is that ,with the 60s Telefunken 12AX7 tubes  that i put in the St-100 , , everything is "clearly" there and laid bare ,so to speak..They are very revealing especially in the top to upper mids.
I think that with different equipment you could get a warmer , tubey sound.The Rogue ST-100 is not warm and tubey sounding .
It has just enough tube character to be smooth. never harsh  and slightly sweet , but only slightly, and  not at all syrupy sweet though..The rogue has the Dyanmics and punch of a solid state amp.
I think the speakers would sound sweeter and more romantic if they were feed that kind of gear. As a matter of fact I think they tend to reveal what your gear is .. good or bad .
I personally love the  the St-100 because of its traits and the Double Impacts reveal that nicely IMO.
Thanks again Bill

In talking with @aniwolfe he made it very good point. If you’re listening levels are say in the 70s, in terms of db levels, the immediacy of the speaker may be very comfortable for you. I listen in the 70s but also into the 80s on my system. 

I also want to state that the speakers had some toe-in. Dennis can give the actual amount of toe-in. It was moderate.

Oh,BTW the Power cables on the MX151 and ST-100 are the Purist Audio Design Dominus  Fluid  cables. The Analog cables from the MX151 to the Rogue are the Purist Audio Dominus Fluid XLR. 

Dennis, room dimensions? 

Do any other SET amplifier owners have a dubious opinion of SET amplifiers that utilize a tetrode/pentode as the power tube?  I mean come on,  its called a single ended triode amplifier for a reason and shouldn't a Triode be employed if for no other reason than name continuity alone; notwithstanding obvious sonic benefits of simplicity, intended application of the proper tube for the proper circuit, and me personally, I don't like my electrons having to jump through additional hoops or grids to get to my ears. Seriously though, am I being a purist snob here? Am I alone in the sentiment that a real set amplifier should have,  at the very least, a real triode tube employed?  Do you roll your eyes when you hear the words "triode mode" as a switchable option on what is most definitely not a set amplifier, at least imho.  Please discuss. I'm dying to get off my high horse and just need to be talked down by some rational banter.  😂  I mean I'd suffer with a parallel set amplifier, but that's where I draw a line in the sand.
